The Society may also commission labora-tory testing, underwater inspection by divers and other

checks carried out by and under the responsibility of quali-fied service suppliers. Survey practices and procedures areselected by the Society at its sole discretion based on itsexperience and knowledge and according to generallyaccepted technical standards in the industry.

Article 33.1. - The class assigned to a yacht reflects the opinion ofthe Society that the yacht, given the intended use andwithin the relevant time frame, complies with the Rulesapplicable at the time the service is rendered. Entry intoforce and application of new Rules are dealt with in Part A,Chapter 1, Section 1, Article 2 of the Rules.3.2. - No report, statement, notation on a plan, review, Cer-tificate of Classification or any document or informationissued or given as part of the services provided by the Soci-ety shall have any legal effect or implication other than arepresentation that the yacht, structure, item of material,equipment or machinery or any other item covered by suchdocument or information meets the Rules. Any such repre-sentation is issued solely for the use ofthe Society, its com-mittees and clients or other duly authorized bodies and forno other purpose.The validity, application, meaning and interpretation of aCertificate of Classification, or any similar document orinformation issued by the Societyin connection with or infurtherance of the performance of its services, is governedby the Rules of the Society, which is the sole subject entitledto their interpretation.Any disagreement on technical matters between the Inter-ested Party and the Surveyor in the carrying out of his func-tions shall be raised in writing as soon as possible with theSociety , which will settle any divergence of opinion or dis-pute.3.3. - The classification of a yacht, or the issuance of a cer-tificate in relation to or in furtherance of the classification ofa yacht or the performance of services by the Society shallhave the validity conferred upon it by the Rules of the Soci-ety at the time of the assignment of class or issuance of thecertificate and in no case shall amount to a representation,statement or warranty of seaworthiness, structural integrity,quality or fitness for a particular purpose or service of anyyacht, structure, material, equipment or machinery sur-veyed by the Society.3.4. - Any document issued by the Society in relation to itsactivities reflects the condition of the yacht at the time ofthe survey, with reference to the applicable Rules. 3.5. - The Rules, surveys performed, reports, certificates andother documents issued by RINA are in no way intended toreplace the duties and responsibilities of other parties suchas Governments, designers, ship builders, manufacturers,repairers, suppliers, contractors or sub-contractors, Ownersor operators, underwriters, sellers or intended buyers of ayacht or other surveyed goods. They do not relieve suchparties from any warranty or responsibility or other contrac-tual obligations expressed or implied or from any liabilitywhatsoever against third parties, nor do they confer on suchother parties any right, claim or cause of action against theSociety.In particular, the above-mentioned activities of the Societydo not relieve the Owner of his duty to ensure the propermaintenance of the yacht at all times.In no case, therefore, the Society shall assume the obliga-tions incumbent upon the above-mentioned parties, evenwhen it is consulted in connection with inquiries concern-

ing matters not covered by its Rules or other documents.Insofar as they are not provided for in the Preamble theduties and responsibilities of the Owner and Interested Par-ties with respect to the services rendered by RINA are out-lined in Part A, Chapter 1, Section 1, Article 3.

Article 44.1. – Any request for any service of the Society shall besubmitted in writing and signed by or on behalf of the Inter-ested Party. Such request will be considered irrevocable assoon as received by the Society and shall entail acceptanceby the applicant of all relevant requirements of the Rules,including the Preamble. Upon acceptance of the written request by the Society , acontract between the latter and the Interested Party isentered into, which is regulated by the present GeneralConditions.4.2. - In consideration of the services rendered by the Soci-ety , the Interested Party and the person applying for the ser-vice shall jointly be liable for the payment of the relevantfees, even if the service is not concluded for any cause nonpertaining to the Society, upon receipt of the invoice andshall reimburse the expenses incurred.

PRINCIPLES OF CLASSIFICATION AND CLASSNOTATIONS

SECTION 1 GENERAL PRINCIPLE OF CLASSIFICATION

SECTION 2 CLASSIFICATION NOTATIONS


Pt A, Ch 1, Sec 1

SECTION 1 GENERAL PRINCIPLE OF CLASSIFICATION

1 Principles of classification

1.1 Purpose of the Rules

1.1.1 The Rules published by RINA give the requirementsfor the assignment, maintenance and the withdrawal ofclass for Yacht engaged in commercial use carrying nocargo and not more than twelve passengers of an overalllength of 24 metres and over. Where necessary, the extentof application is more precisely defined in each part ofthese rules.

Class assigned to a yacht reflects the discretionary opinionof RINA that the yacht, for declared conditions of use andwithin the relevant time frame, complies with the Rulesapplicable at the time the service is rendered

.

Note 1: The general conditions of classification are laiddown in the Preamble.

The application criteria of the different parts of the presentRules are the following:

• Part A - Classification and Surveys

• Part B - Hull

• Part C - Machinery, Electrical installations and Automa-tion

• Part D - Materials and Welding

• Part E - Safety Rules

• Part F - Additional Class Notations.

Part E incorporates the text in full of the safety codes issuedby the flag administrations whose flag the yacht is intendedto fly. The parts in Part E identified by a vertical line placedin the margin of the text are not applicable for the purposeof classification.

Parts from A to D and applicable parts of Part E are applied,as a minimum, for the purpose of classification.

Part F applies at the request of the interested party for theassignment of additional class notations.

1.2 General definitions

1.2.1 The following general definitions are used in theseRules:

a) Yacht means a vessel which is engaged in commercialuse for sport or pleasure, do not carry cargo and do notcarry more than 12 passengers; the vessel may be pro-

pelled machanically, by sail or by a combination ofboth;

b) Rules means these Rules for the Classification of CharterYachts;

c) Surveyor means technical staff acting on behalf of RINAto perform tasks in relation to classification and surveyduties;

d) Survey means an intervention by the Surveyor forassignment or maintenance of class as defined in Chap-ter 2, or interventions by the Surveyor within the limitsof the tasks delegated by the Administrations;

e) Administration means the Government of the Statewhose flag the yacht is entitled to fly;

f) Interested Party means a party, other than RINA, havingresponsibility for the classification of the yacht, such asthe Owner of the yacht and his representatives, or theShipbuilder, or the Engine Builder, or the Supplier ofparts to be tested. Owner means the Registered Owneror the Disponent Owner or the Manager or any otherparty having the responsibility to keep the yacht seawor-thy, having particular regard to the provisions relating tothe maintenance of class laid down in Chapter 2;

g) Approval means the examination and acceptance byRINA of documents, procedures or other items relatedto classification, verifying solely their compliance withthe relevant Rules requirements;

h) Type approval means an approval process for verifyingcompliance with the Rules of a product, a group ofproducts or a system, and considered by RINA as repre-sentative of continuous production;

i) Essential service is intended to mean a service necessaryfor a yacht to proceed at sea, be steered or manoeuvred,or undertake activities connected with its operation, andfor the safety of life, as far as class is concerned.

1.3 Meaning of classification, scope and limits

1.3.1 The classification consists of:• the development of Rules, guidance notes and other

documents relevant to the yacht, structure, material,equipment, machinery and any other item covered bysuch documents;

• the examination of plans and calculations and the sur-veys, checks and tests intended to ensure that the yachtmeets the Rules (refer to Ch 2, Sec 1);

• the assignment of class (see Ch 2, Sec 1) and issue of aCertificate of Classification, where the above Rules aremet;

• the periodical, occasional and class renewal surveysperformed to verify that the yacht in service meets theconditions for maintenance of class (see Ch 2, Sec 2).


Pt A, Ch 1, Sec 1

1.3.2 The Rules, surveys performed, reports, certificatesand other documents issued by RINA, are in no wayintended to replace or alleviate the duties and responsibili-ties of other parties such as Administrations, Designers,Shipbuilders, Manufacturers, Repairers, Suppliers, Contrac-tors or Sub-contractors, actual or prospective Owners orOperators, Charterers, Brokers and Underwriters.

RINA cannot therefore assume the obligations arising fromthese functions, even when RINA is consulted to answerinquiries concerning matters not covered by its Rules, orother documents.

The activities of such parties which fall outside the scope ofthe classification as set out in the Rules, such as design,engineering, manufacturing, operating alternatives, choiceof type and power of machinery and equipment, numberand qualification of crew or operating personnel, hull vibra-tions, spare parts including their number, location and fas-tening arrangements, life-saving appliances, andmaintenance equipment, remain therefore the responsibilityof those parties, even if these matters may be given consid-eration for classification according to the type of yacht oradditional class notation assigned.

The classification-related services and documents per-formed and issued by RINA do not relieve the parties con-cerned of their responsibilities or other contractualobligations expressed or implied or of any liability whatso-ever, nor do they create any right or claim in relation toRINA with regard to such responsibilities, obligations andliabilities.

In particular, RINA does not declare the acceptance or com-missioning of a yacht or any part of it, this being the exclu-sive responsibility of the Owner.

Unless otherwise specified, the Rules do not deal withstructures, pressure vessels, machinery and equipment thatare not permanently installed on board. During periods ofconstruction, modification or repair, the unit is solely underthe responsibility of the builder or the repair yard. As anexample, the builder or repair yard is to ensure that the con-struction, modification or repair activities are compatiblewith the design strength of the yacht and that no permanentdeformations are sustained.

1.3.3 In the case of a dual classed yacht, certificatesrelated to statutory requirements may be issued by the otherclassification society, provided it is recognised in a formaldual class agreement with RINA and provided that is alsoauthorized by the national authority.

1.4 Request for services

1.4.1 Requests for interventions by RINA, such as surveysduring construction, surveys of yachts in service, tests, etc.,are in principle to be submitted in writing and signed by theInterested Party. Such request implies that the applicant willabide by all the relevant requirements of the Rules, includ-ing its Preamble.

RINA reserves the right to refuse or withdraw the class ofany yacht for which any applicable requirement of theRules is not complied with.

2 Rules

2.1 Effective date

2.1.1 The effective date of entry into force of any amend-ments to the Rules is indicated on the inside front page ofeach Part of the Rules.

2.1.2 In principle, the applicable Rules for assignment ofclass to a new yacht are those in force at the date when theshipyard makes an application for surveillance of construc-tion of a new yacht.

2.1.3 Special consideration may be given to applying newor modified rule requirements which entered into force sub-sequent to the date of request of interventions by RINA fromshipyard, at the discretion of RINA and in the followingcases:

• when a justified written request is received from theparty applying for classification

• where it is intended to use existing previously approvedplans for a new contract.

2.1.4 The above procedures for application of the Rulesare, in principle, also applicable to existing yachts in thecase of major conversions and, in the case of alterations, tothe altered parts of the yacht.

2.1.5 The rule requirements related to assignment, mainte-nance and withdrawal of the class of yacht already in oper-ation, as detailed in Chap 2 Sect 1 to Chap 2 Sect 3, areapplicable from the date of their entry into force.

2.2 Equivalence

2.2.1 RINA may consider the acceptance of alternatives tothese Rules, provided that they are deemed to be equivalentto the Rules to the satisfaction of RINA.

2.3 Novel features

2.3.1 RINA may consider the classification of yachtsbased on or applying novel design principles or features, towhich the Rules are not directly applicable, on the basis ofexperiments, calculations or other supporting informationprovided to RINA. The specific limitations may then be indi-cated on the Certificate of Classification.

2.4 Interpretation

2.4.1 RINA alone is qualified to decide upon the meaning,interpretation and application of the Rules and other classi-fication-related documents. No reference to the Rules orother classification-related documents has any value unlessit involves, accompanies or follows the intervention ofRINA.


Pt A, Ch 1, Sec 1

2.5 Disagreement and appeal

2.5.1 Any technical disagreement with the Surveyor inconnection with the performance of his duties should beraised by the Interested Party as soon as possible.

The Interested Party may appeal in writing to RINA, whichwill subsequently consider the matter and announce itsdecision according to its established procedure.

3 Interested Parties responsibilities

3.1 International and national regulations

3.1.1 The classification of a yacht does not absolve theInterested Party from compliance with any requirementsissued by Administrations and any other applicable interna-tional and national regulations for the safety of life at seaand protection of the marine environment.

3.1.2 Even if a yacht is provided with a class certificate asa charter yacht, in order to employ it in charter services, theAdministration, whose flag the yacht is flying, or otherauthorized Society shall issue to the yacht the relevantsafety certificates.

3.1.3 When authorized by the Administration concerned,RINA will act on its behalf within the limits of such authori-sation. In this respect, RINA will take into account the rele-vant national requirements, survey the yacht, report andissue or contribute to the issue of the corresponding certifi-cates.

The above surveys do not fall within the scope of the classi-fication of yachts, even though their scope may overlap inpart and may be carried out concurrently with surveys forassignment or maintenance of class.

3.1.4 In the case of a discrepancy between the provisionsof the applicable international and national regulations andthose of the Rules, normally, the former take precedence.

However, RINA reserves the right to call for the necessaryadaptation to preserve the intention of the Rules or to applythe provisions of [1.4.1].

3.2 Surveyor’s intervention

3.2.1 Surveyors are to be given free access at all times toyachts which are classed or being classed, shipyards andworks, to carry out their interventions within the scope ofassignment or maintenance of class, or within the scope ofinterventions carried out on behalf of Administrations,whenso delegated.

Free access is also to be given to auditors accompanying theSurveyors of RINA within the scope of the vertical audits asrequired in pursuance of RINA's internal Quality System oras required by external organizations.

3.2.2 Interested Parties are to take the necessary measuresfor the Surveyors' inspections and testing to be carried outsafely. Interested Parties - irrespective of the nature of theservice provided by the Surveyors of RINA or others actingon its behalf - assume with respect to such Surveyors all theresponsibility of an employer for his workforce such as to

meet the provisions of applicable legislation. As a rule, theSurveyor is to be constantly accompanied during surveys bypersonnel of the Interested Party.

Refer also to Ch 2, Sec 2, [2.4] to Ch 2, Sec 2, [2.7].

3.2.3 The Certificate of Classification and/or other docu-ments issued by RINA remain the property of RINA. All cer-tificates and documents necessary to the Surveyor'sinterventions are to be made available by the InterestedParty to the Surveyor on request.

3.2.4 During the phases of yacht design and construction,due consideration should be given to rule requirements inrespect of all necessary arrangements for access to spacesand structures with a view to carrying out class surveys.Arrangements of a special nature are to be brought to theattention of RINA.

3.3 Operation and maintenance of yachts

3.3.1 The classification of a yacht is based on the under-standing that the yacht is operated according to manufac-turer's recommendation, in a proper manner by competentand qualified crew or operating personnel according to theloading, environmental, operating and other criteria onwhich classification is based.

In particular, it will be assumed that the draught of the yachtin operating conditions will not exceed that correspondingto the freeboard assigned or the maximum approved for theclassification, that the yacht will be properly used takinginto account both its stability and the stresses imposed onits structures, where applicable. That the speed and courseof the yacht are adapted to the prevailing sea and weatherconditions according to the normal prudent seamanshipand that the yacht is operated in accordance with the appli-cable international and national regulations for the preven-tion and containment of marine pollution.

3.3.2 Any document issued by RINA in relation to its inter-ventions reflects the condition of the yacht as found at thetime and within the scope of the survey. It is the InterestedParty's responsibility to ensure proper maintenance of theyacht until the next survey required by the Rules. It is theduty of the Interested Party to inform the Surveyor when heboards the yacht of any events or circumstances affectingthe class.

3.3.3 Any damage or defect which could invalidate theconditions for which the class has been assigned, is to becommunicated to RINA without delay.

3.4 Use of measuring equipment and of service suppliers

3.4.1 GeneralFirms providing services on behalf of the Interested Party,such as measurements, tests and servicing of safety systemsand equipment, the results of which may form the basis forthe Surveyor's decisions, are subject to the acceptance ofRINA, as deemed necessary.

The equipment used during tests and inspections in work-shops, shipyards and on board yachts, the results of which


Pt A, Ch 1, Sec 1

may form the basis for the Surveyor's decisions, is to be cus-tomary for the checks to be performed. Firms are to individ-ually identify and calibrate to a recognised national orinternational standard each piece of such equipment.

3.4.2 Simple measuring equipmentThe Surveyor may accept simple measuring equipment (e.g.rulers, tape measures, weld gauges, micrometers) withoutindividual identification or confirmation of calibration, pro-vided it is of standard commercial design, properly main-tained and periodically compared with other similarequipment or test pieces.

3.4.3 Shipboard measuring equipmentThe Surveyor may accept measuring equipment fitted onboard a yacht (e.g. pressure, temperature or rpm gauges andmeters) and used in examination of shipboard machineryand/or equipment based either on calibration records orcomparison of readings with multiple instruments.

3.4.4 Other equipment

The Surveyor may request evidence that other equipment(e.g. tensile test machines, ultrasonic thickness measure-ment equipment, etc) is calibrated to a recognized nationalor international standard.

3.5 Spare parts

3.5.1 It is the Owner's responsibility to decide whetherand which spare parts are to be carried on board.

3.5.2 As spare parts are outside the scope of classification,the Surveyor will not check that they are kept on board,maintained in a satisfactory condition, or suitably protectedand lashed. However, in the case of repairs or replacement,the spare parts used are to meet the requirements of theRules as far as practicable; refer to Ch 2, Sec 2, [5.3.2].

• classed with an IACS Society, or

• classed with other Society.

3.2 Yachts classed with an IACS Society

3.2.1 GeneralIn this case, yacht will be admitted to the RINA's class uponsatisfactory surveys and verification of documentation. Forthe extent and scope of the surveys to be carried out and the

list of documentation to be submitted by the InterestedParty, reference is to be made to [3.2.2] and [3.2.3] below.

3.2.2 SurveysSurveys to be carried out are based on the age of the vesseland the updated current class status as provided by the pre-vious IACS Member Society. In general and at the discretionof RINA, the extent of these surveys is to be at least the fol-lowing.

a) Surveys of hull:• for vessels of age less than 10 years the survey is to

have the scope of an intermediate survey;• for vessels between 10 and 15 years of age, in addi-

tion, the survey is to include the inspection of a rep-resentative number of internal compartment, theinspection of the chain locker (cleared and cleaned)and thickness measurements , if considered neces-sary by the Surveyor. The interior of the yacht shallbe sufficiently opened out by the removal of lining,ceiling, cabin sole at the discretion of the Surveyorwho shall be satisfied of the condition of the struc-ture. In the context of applying this case, if a bottomsurvey in dry condition of the vessel is not due at thetime of transfer, consideration can be given to carry-ing out an underwater examination in lieu of thebottom survey in dry condition;

• for all yachts which are 15 years of age and above afull class renewal survey, together with a dry bottomsurvey, is to be carried out. In exceptional casesconsideration can be given to carrying out an under-water examination in lieu of the bottom survey indry condition;

Pt A, Ch 2, Sec 1

4 Date of initial classification

4.1 Definitions

4.1.1 Date of buildFor a new building the date of build is the year and monthat which the new construction survey process is completed. Where there is a substantial delay between the completionof the construction survey process and the yacht commenc-ing active service, the date of commissioning may be alsospecified. If modifications are carried out, the date of build remainsassigned to the yacht. Where a complete replacement oraddition of a major portion of the yacht (e.g. forward sec-tion, after section) is involved, the following applies:• the date of build associated with each major portion of

the yacht is indicated on the classification certificate;• survey requirements are based on the date of build asso-

ciated with each major portion of the yacht.

4.1.2 Date of initial classification for new buildingsAs a general rule, for new buildings the date of initial classi-fication coincides with the date of build.

4.1.3 Date of initial classification for existing yachts

In principle, for existing yacht the date of initial classifica-tion is the date of completion of the admission to class sur-vey.

4.1.4 Period of classThe assigned period of class is never to exceed five (5)years. The 5 year period is granted only upon completion ofthe new building procedure and, for yachts classed afterconstruction, upon satisfactory outcome of a survey withthe scope of a renewal survey. If a yacht classed after con-struction was previously classed with an IACS MemberSociety [3.2], the assigned period of class is never to go

beyond the due date of the renewal survey assigned by theprevious IACS Society.

5 Reassignment of class

5.1 General

5.1.1 At the request of the Owner and for a yacht previ-ously classed and subsequently withdrawn from class, mayhave the class reassigned subject to an admission to classsurvey. Details of the admission survey will be consideredby RINA for each single case and if applicable and appro-priate, account may be taken of any periodical surveys heldin the former period of class.

6 Double or dual class procedure

6.1 Definitions

6.1.1 A "double class" yacht is one which is classed by twoClassification Societies, where each one works as if it is theonly Society classing the yacht, and does all surveys inaccordance with its own requirements and schedule.

6.1.2 A "dual class" yacht is one which is classed by twoClassification Societies between which there is a writtenagreement regarding sharing of work, reciprocal recogni-tion of surveys carried out by each of the Societies on behalfof the other and full exchange of information on the classstatus and survey reports.

6.2 Procedure

6.2.1 The procedure of admission to class of a yacht,already classed with another IACS Society, under double ordual class arrangement is to be the same as that providedfor single class arrangement.

SECTION 2 MAINTENANCE OF CLASS

1 General principles of surveys

1.1 Survey types

1.1.1 All classed yachts are submitted to surveys for themaintenance of class. These surveys include the classrenewal survey, intermediate survey, bottom survey (eithersurvey in dry condition or in-water survey), tailshaft survey,boiler survey, and surveys for the maintenance of additionalclass notations, where applicable.Such surveys are carried out at the intervals and under theconditions laid down in this Section. In addition to theabove periodical surveys, yachts are to be submitted tooccasional surveys whenever the circumstances so require;refer to [5].

1.1.2 The different types of periodical surveys are summa-rized in Tab 1. The intervals at which the periodical surveysare carried out are given in the items referred to in the sec-ond column of Tab 1. The relevant extent and scope aregiven in Chapter 3 while surveys related to additional classnotations are given in Chapter 4.

Where there are no specific survey requirements for addi-tional class notations assigned to a yacht, equipment and/orarrangements related to these additional class notations areto be examined, as applicable, to the Surveyor's satisfactionat each class renewal survey for the class.

The surveys are to be carried out in accordance with the rel-evant requirements in order to confirm that the hull,machinery, equipment and appliances comply with theapplicable Rules and will remain in satisfactory conditionbased on the understanding and assumptions mentioned inCh 1, Sec 1, [3.3].

Where the conditions for the maintenance of class andadditional class notations are not complied with, the classand/or the additional class notations as appropriate will besuspended and/or withdrawn in accordance with the appli-cable Rules given in Sec 3.

Note 1: It is understood that requirements for surveys apply tothose items that are required according to the Rules or, even if notrequired, are fitted on board.

Table 1 : List of Periodical Surveys

1.2 Change of periodicity, postponement or advance of surveys

1.2.1 RINA reserves the right, after due consideration, tochange the periodicity, postpone or advance surveys, takinginto account of particular circumstances.

1.2.2 When a survey becomes overdue during a voyage,the following applies:

a) In the case of a class renewal survey, RINA may, underexceptional circumstances, grant an extension to allowfor completion of this survey provided there is docu-mented agreement to such an extension prior to theexpiry date of the Certificate of Classification, adequate

arrangements have been made for the attendance of theSurveyor at the first port of call and RINA is satisfied thatthere is technical justification for such an extension.Such an extension will be granted only until arrival atthe first port of call after the expiry date of the Certificateof Classification.

b) In the case of intermediate surveys, no postponement isgranted. Such survey is to be completed within its pre-scribed windows; see [2.1.3]

c) In the case of all other periodical surveys and recom-mendations, extension of class may be granted until thearrival of the yacht at the port of destination.

1.3 Extension of scope of survey

1.3.1 RINA and/or its Surveyors may extend the scope ofthe provisions in Chapter 3 and Chapter 4, which set forththe technical requirements for surveys, whenever and so faras considered necessary, or modify them in the case of spe-cial yachts or systems.

1.3.2 The extent of any survey also depends upon the con-dition of the yacht and its equipment. Should the Surveyorhave any doubt as to the maintenance or condition of theyacht or its equipment, or be advised of any deficiency ordamage which may affect the class, then further examina-tion and testing may be conducted as considered necessary.

1.3.3 In case RINA has cause to believe that its rules arebeing not complied with, RINA reserves the right to performunscheduled surveys.

1.4 General procedure of survey

1.4.1 The general procedure of survey consists in:

• an overall examination of the parts of the yacht coveredby the rule requirements

• checking selected items covered by the rule require-ments

• attending tests and trials where applicable and deemednecessary by the Surveyor.

1.4.2 RINA's survey requirements cannot be considered asa substitute for specification and acceptance of repairs andmaintenance, which remain the responsibility of theOwner.

1.4.3 In accordance with the provisions of Ch 1, Sec 1,[3.1], RINA will, at the request of the Owner, apply the reg-ulations of Administrations concerning the scope and perio-dicity of surveys when they differ from those laid down inPart A.

1.4.4 During the surveys, the Surveyor does not check thatthe spare parts are kept on board, maintained in workingorder and suitably protected and lashed.

1.5 Appointment of another Surveyor

1.5.1 In compliance with the provisions of Ch 1, Sec 1,[2.5.1], should a disagreement arise between the Ownerand the Surveyor during a survey, RINA may, at the requestof the Owner, designate another Surveyor.

2 Definitions and procedures related to surveys

2.1 General

2.1.1 Period of class

Period of class means the period starting either from thedate of the initial classification, see Sec 1, [4], or from the

credited date of the last class renewal survey, and expiringat the limit date assigned for the next class renewal survey

2.1.2 Anniversary date

Anniversary date means the day of the month of each yearin the period of class that corresponds to the expiry date ofthe period of class.

2.1.3 Survey time window

Survey time window or more simply window, means thefixed period during which annual and intermediate surveysare to be carried out.

2.1.4 Overdue surveys

Each periodical survey is assigned a limit date specified bythe relevant requirements of the Rules (end of survey inter-val or end date of window) by which it is to be completed.A survey becomes overdue when it has not been completedby its limit date.

2.1.5 Recommendations

Any defect and/or deficiency affecting the class and to bedealt with within a specific period of time is indicated as arecommendation. A recommendation is pending until it iscleared. Where it is not cleared by its limit date, the recom-mendation is overdue and the class is automatically sus-pended.

2.1.6 Memoranda

Those defects and/or deficiencies which do not affect themaintenance of class and which may therefore be cleared atthe Owner's convenience and any other informationdeemed noteworthy for RINA's convenience are indicatedas memoranda. Memoranda are not to be regarded as rec-ommendations.

2.1.7 Ballast Tank

A Ballast tank means a tank that is used primarily for saltwa-ter ballast.

2.1.8 Spaces

Those spaces which are intended to separate hull compart-ments including integral tanks.

2.1.9 Overall survey

An overall survey is a survey intended to report on the over-all condition of the hull structure and determine the extentof additional close-up surveys.

2.1.10 Transverse section

A transverse section includes all longitudinal members con-tributing to longitudinal hull girder strength, such as plating,longitudinals and girders at the deck, side shell, bottom,inner bottom, longitudinal bulkheads, as well as relevantlongitudinals. For a transversely framed yacht, a transversesection includes adjacent frames and their end connectionsin way of transverse sections.


Pt A, Ch 2, Sec 2

2.1.11 Suspect areasSuspect areas are locations showing substantial corrosionand/or considered by the Surveyor to be prone to rapidwastage and may include:

a) For steel hulls, areas of substantial corrosion and/orfatigue cracking

b) For aluminium alloy hulls, areas of fatigue cracking andareas in the vicinity of bimetallic connections.

c) For composite hulls, areas subject to impact damageand/or slamming.

d) For wood hulls, areas subject to deterioration as a resultof fresh water ingress or poor ventilation.

e) For sailing craft, areas subject to high local stresses dueto rigging loads and ballast keel attachments.

2.1.12 Substantial corrosionSubstantial corrosion is an extent of corrosion such thatassessment of the corrosion pattern indicates a wastage inexcess of 75% of allowable margins, but within acceptablelimits.

2.1.13 Protective coatingsA corrosion prevention system is normally consideredeither:

• a full hard coating, or

• a full hard coating supplemented by anodes.

Protective coating should usually be epoxy coating orequivalent. Other coating systems (soft coating) may beconsidered acceptable as alternatives provided that they areapplied and maintained in compliance with the Manufac-turer's specifications.

2.1.14 Coating conditionCoating condition for steel yacht is defined as follows:

• GOOD: condition with only minor spot rusting

• FAIR: condition with local breakdown at edges of stiff-eners and weld connections and/or light rusting over20% or more of areas under consideration, but less thanas defined for poor condition

• POOR: condition with general breakdown of coatingover 20% or more of areas or hard scale at 10% or moreof areas under consideration.

2.1.15 Prompt and Thorough Repair A Prompt and Thorough Repair is a permanent repair com-pleted at the time of survey to the satisfaction of the Sur-veyor, therein removing the need for the imposition of anyassociated recommendation.

2.2 Procedures for thickness measurements

2.2.1 When required as per the scope of surveys definedbelow, thickness measurements are normally to be carriedout under the responsibility of the Owner, in the presenceof the Surveyor. The Surveyor is to be on board to the extentnecessary to control the process.

2.2.2 In general thickness measurements are to be carriedout by a company recognized by RINA.

2.2.3 A thickness measurement report is to be prepared.The report is to give the location of measurements, thethickness measured and the corresponding original thick-ness.

Furthermore, the report is to include the date when themeasurements were carried out, the type of measuringequipment, the names and the qualification of the operatorsand their signatures.

The report is to be validated by the Surveyor.

2.2.4 For acceptance criteria applicable to structural corrosiondiminution levels, reference is to be made to App 1.

2.2.5 The yacht's longitudinal strength is to be evaluatedby using the thickness of structural members measured,renewed and reinforced, as appropriate, during the classrenewal survey carried out after the yacht reached 20 yearsof age in accordance with the criteria for longitudinalstrength of the yacht's hull girder specified in App 1.

The Surveyor may extent the scope of thickness measure-ments if deemed necessary. Suspected areas, as defined in[2.1.11], which may include areas where the coatings arefound FAIR or POOR, may be inspected every time the Sur-veyor considers it necessary.

2.3 Agreement of firms for in-water survey

2.3.1 The in-water surveys referred to in the Rules are tobe carried out by a certified company accepted or recog-nized by RINA.

2.4 Conditions for surveys

2.4.1 The Owner is to provide the necessary facilities forthe safe execution of the surveys, as per Ch 1, Sec 1,[3.2.2].

2.4.2 For their internal examination, tanks and spaces areto be safe for access, i.e. gas freed, ventilated and illumi-nated.

In preparation for survey and thickness measurements andto allow for a thorough examination, all spaces are to becleaned including removal from surfaces of all loose accu-mulated corrosion scale. Spaces are to be sufficiently cleanand free from water, scale, dirt, oil residues etc. to revealcorrosion, deformation, fractures, damage, or other struc-tural deterioration. However, those areas of structure whoserenewal has already been decided by the Owner need onlybe cleaned and descaled to the extent necessary to deter-mine the limits of the renewed areas.

Illumination is to be provided to reveal significant corro-sion, deformation, fractures, damage or other structuraldeterioration.

2.4.3 A tank entry permit is to be issued prior to enteringthe tank. Adequate ventilation is to be maintained duringthe survey, and the required ventilation is to be specified onthe entry permit.

2.4.4 When necessary (yachts with tanks of great dimen-sions), a communication system is to be arranged between


Pt A, Ch 2, Sec 2

the survey party in the tank and the responsible officer ondeck.

2.4.5 When examination of associated structure isrequired, the following applies:

• the interior of the yacht is to be opened out (for such anextension as deemed necessary by the Surveyor) byremoval of lining, ceiling/cabin sole. In all these cases,the areas where linings/ ceilings have been opened upshall be recorded in the report of survey. This record willbe utilized for reference for the successive surveys;

• ceilings in compartments and floors in the engine roomare to be lifted to the necessary extent for examinationof the structure below;

• machinery compartments and peaks have to be cleaned;

• where spaces are insulated, insulation is to be removedfor the extension deemed necessary by the Surveyor;

• Linings, ceiling/cabin soles are to be removed asrequired by the Surveyor in order to be satisfied of theconditions of the structure;

• cement or other protective sheathing is to be removedwhen there is any doubt as to the condition of the plat-ing underneath or when adherence to plating is nottight;

• in the case of solid ballast spaces, the solid ballast is tobe partially removed for examination of the condition ofthe structure in way. Should doubts arise, the Surveyormay require more extensive removal of the solid ballast;

• insulation of compartments intended for storage ofrefrigerated goods is to be removed over the necessaryextent for examination by the Surveyor of the conditionof the structure, unless constructional arrangementsmake such inspections possible without removing theinsulation;

• where soft coatings have been applied, safe access is tobe provided for the Surveyor to verify the effectivenessof the coating and to carry out an assessment of the con-ditions of internal structures which may include spotremoval of the coating. When safe access cannot beprovided, the soft coating is to be removed.

2.5 Access to structures

2.5.1 For overall survey, means are to be provided to ena-ble the Surveyor to examine the structure in a safe and prac-tical way.

2.6 Equipment for surveys

2.6.1 One or more of the following fracture detectionmethods may be required if deemed necessary by the Sur-veyor:

• radiography (X or γ rays)

• ultrasonic test

• magnetic particle test

• dye penetrant test.

2.6.2 Thickness measurement is normally to be carried outby means of ultrasonic test equipment. The accuracy of theequipment is to be proven to the Surveyor as required.

2.7 Surveys at sea and anchorage

2.7.1 Surveys at sea or at anchorage may be accepted pro-vided the Surveyor is given the necessary assistance by thepersonnel on board. Precautions and procedures for carry-ing out the survey are to be in accordance with [2.4], [2.5]and [2.6].

2.8 Repairs and maintenance during voyage

2.8.1 Where repairs to hull, machinery or other equip-ment, which affect or may affect the class, are to be carriedout by a riding crew during a voyage, they are to beplanned in advance. A complete repair procedure includingthe extent of proposed repair and the need for the Sur-veyor's

attendance during the voyage is to be submitted to RINA forapproval sufficiently in advance. Failure to notify RINA inadvance of the repairs may result in the suspension of classof the yacht.

2.8.2 The above is not intended to include maintenance toand overhaul of the hull, machinery and equipment inaccordance with the Manufacturer's recommended proce-dures and established marine practice, which does notrequire RINA's agreement. However, any repair resultingfrom such maintenance and overhauls which affects or mayaffect the class is to be noted in the yacht's log and submit-ted to the attending Surveyor for use in determining furthersurvey requirements.

2.9 Prompt and thorough repairs

2.9.1 Any damage in association with wastage over theallowable limits (including buckling, grooving, detachmentor fracture), or extensive areas of wastage over the allowa-ble limits, which affects or, in the opinion of the Surveyor,will affect the vessel's structural, watertight or weathertightintegrity, is to be promptly and thoroughly (see [2.1.15])repaired. Areas to be considered include, as far as applica-ble, the following:

- side structure and side plating;

- deck structure and deck plating;

- bottom structure and bottom plating;

- inner bottom structure and inner bottom plating;

- inner side structure and inner side plating;

- longitudinal bulkhead structure and longitudinal bulk-head plating, where fitted;

- transverse watertight bulkhead structure and transversewatertight bulkheads plating;

Where adequate repair facilities are not available, consider-ation may be given to allow the vessel to proceed directly toa repair facility. This may require temporary repairs for theintended voyage.

2.9.2 Additionally, when a survey results in the identifica-tion of substantial corrosion or structural defects, either ofwhich, in the opinion of the Surveyor, will impair theyacht's fitness for continued service, remedial measures areto be implemented before the yacht continues in service.


Pt A, Ch 2, Sec 2

3 Certificate of Classification: issue, validity, endorsement and renewal

3.1 Issue of Certificate of Classification

3.1.1 A Certificate of Classification, bearing the class nota-tions assigned to the yacht and an expiry date, is issued toany classed yacht.

3.1.2 A Provisional Certificate of Classification may serveas a Certificate of Classification in some cases, such as afteran admission to class survey, or when RINA deems it neces-sary.

3.1.3 The Certificate of Classification or Provisional Certif-icate of Classification is to be made available to the RINA'sSurveyors upon request.

3.2 Validity of Certificate of Classification, maintenance of class

3.2.1 According to Ch 1, Sec 1, [2.4], RINA alone is qual-ified to confirm the class of the yacht and the validity of itsCertificate of Classification.

3.2.2 During the class period, a Certificate of Classifica-tion is valid when it is not expired. The class is maintainedduring a certain period or at a given date, when during thesaid period or at such date the conditions for suspension orwithdrawal of class are not met.

3.2.3 At the request of the Owner, a statement confirmingthe maintenance of class may be issued by RINA based onthe information in its records for that yacht at the time.This statement is issued on the assumption that the Ownerhas complied with the Rules, in particular with [5]. Shouldany information which would have prevented RINA fromissuing the statement and which was not available at thetime subsequently come to light, the statement may be can-celled. Attention is drawn to Sec 3, [1.2], whereby RINA,upon becoming aware of a breach of the Rules, is empow-ered to suspend class from the date of the breach, whichmay be prior to the date of the statement.

3.2.4 According to the same conditions as in [3.2.3], astatement declaring that the class is maintained "clean andfree from recommendation'' may be issued by RINA whenthere is no pending recommendation at that date.

3.2.5 Classification-related documents and informationare liable to be invalidated by RINA whenever their objectis found to differ from that on which they were based or tobe contrary to the applicable requirements. The Owner isliable for any damage which may be caused to any thirdparty from improper use of such documents and informa-tion.

3.3 Endorsement of Certificate of Classifica-tion

3.3.1 Text of endorsement When surveys are satisfactorily carried out, the Certificateof Classification is generally endorsed accordingly, except

as stipulated in the last sentence of this paragraph. Eachendorsement normally consists of a description summaris-ing the surveys held and a conclusion stating the conse-quent class position of the yacht. In special cases theendorsement may include additional indications such asmodifications to classification notations, limits imposed onnavigation, special restrictions, etc.

3.3.2 Possible modifications to endorsementsRINA reserves the right to modify the endorsements madeby Surveyors.

3.4 Status of surveys and recommendations

3.4.1 Information given in the Certificate of Classification,associated endorsements, Rules and specific documentsenables the Owner to identify the status of surveys and rec-ommendations.

3.4.2 The omission of such information does not absolvethe Owner from ensuring that surveys are held by the limitdates and pending recommendations are cleared to avoidany inconvenience which is liable to result from the suspen-sion or withdrawal of class; see Sec 3.

4 Class renewal Surveys


4.1.1 The first class renewal survey is to be completedwithin 5 years from the date of the initial classification sur-vey and thereafter 5 years from the credited date of the pre-vious class renewal survey. However, consideration may begiven by RINA to granting an extension for a maximum ofthree months after the limit date, in exceptional circum-stances and provided that the yacht is attended and theattending Surveyor so recommends. In such cases the nextperiod of class will start from the limit date for the previousclass renewal survey before the extension was granted.

4.1.2 For surveys completed within 3 months before thelimit date of the class renewal survey, the next period ofclass will start from this limit date. For surveys completedmore than three months before the limit date, the period ofclass will start from the survey completion date.

4.1.3 A new period of class is assigned to the yacht afterthe satisfactory completion of the class renewal survey, anda new Certificate of Classification is issued for the newperiod of class.

The class renewal survey may be carried out during twelvemonths before the limit date of the class renewal survey.The next due date will be in accordance with [4.1.1] and[4.1.2].

4.2 Intermediate surveys

4.2.1 An intermediate survey, is to be carried out withinthe window from three months before the second to threemonths after the third anniversary date. I.e: two and a halfyears after the delivery or anniversary date with a surveytime window plus / minus nine months.


Pt A, Ch 2, Sec 2

4.3 Bottom survey

4.3.1 Bottom survey means the examination of the outsideof the yacht's bottom and related items. This examinationmay be carried out with the yacht either in dry dock (or on aslipway) or afloat: in the former case the survey will bereferred to as dry-docking survey, while in the latter case asin-water survey.

4.3.2 The Owner shall notify RINA each time the outsideof the yacht's bottom and related items can be examined indry dock or on a slipway.

4.3.3 There is to be a minimum of two examinations of theoutside of the yacht's bottom and related items during eachfive-year class renewal survey period. One such examina-tion isto be carried out in conjunction with the special sur-vey. In all cases the interval between any two suchexaminations is not to exceed 36 months. Considerationmay be given at the discretion of RINA to any special cir-cumstances justifying an extension of these intervals.Note 1: Attention is drawn to the relevant requirements of Ch 1,Sec 1, [3.1], concerning application of national and internationalregulations.

4.3.4 Examinations of the outside of yacht's bottom andrelated items of yacht are normally to be carried out withthe yacht in drydock. However, consideration may be givento alternate examination while the yacht is afloat as an In-water Survey, subject to the provisions of Ch 3, Sec 3, [3].Special consideration is to be given to yachts of 15 years orover before being permitted to have such examinations.


4.4.1 DefinitionTailshaft survey means survey of propeller shafts and tubeshafts (hereafter referred to as tailshafts) as well as survey ofother propulsion systems.

4.4.2 Tailshaft complete survey Following tailshafts are subject to be submitted to completeexamination at intervals not exceeding five years:• where the propeller is fitted keyless, the shaft is pro-

tected from sea water or made of corrosion resistantmaterial or fitted with oil glands, the design details areapproved, and a non-destructive examination of the for-ward part of the aft shaft taper is performed at each sur-vey by an approved crack-detection method;

• where the propeller is fitted to a keyed shaft taper thedesign details of which comply with the applicablerequirements in Pt C, Ch 1, Sec 6, the shaft is fitted withcontinuous liners, or approved oil sealing glands, ormade of corrosion-resistant material and a nondestruc-tive examination of the after end of the cylindrical partof the shaft (from the after end of the liner, if any), and ofabout one third of the length of the taper from the largeend is performed at each survey by an approved crack-detection method with the key removed;

• where the propeller is fitted to a solid flange coupling atthe aft end of the shaft, the shaft is and its fittings are notexposed to corrosion or made of a corrosion resistantmaterial or fitted with oil glands, the design details are

approved, and a non-destructive examination of theafter flange fillet area of the shaft is performed at eachsurvey by an approved crack-detection method.

In all other cases, the periodicity of the complete survey istwo and a half years (two years and six months).

Consideration may be given at the discretion of RINA to anyspecial circumstances justifying an extension of these inter-vals.

During the survey, in addition to the non destructive exami-nation of the forward part of the aft shaft taper, even theafter end of the cylindrical part of the shaft is to be exam-ined with the same method. Furthermore, weardown is tobe measured and the sterntube bearings, oil glands, propel-lers and fastenings are to be examined.

Water jet units are to be dismantled for examination of theimpeller, casing, shafts, shaft seal and bearing, inlets andoutlets channels, steering nozzle, reversing arrangementand control gear.

4.4.3 Tailshaft modified surveyA modified survey of the tailshaft is an alternate way ofexamination whose scope is given in Ch 3, Sec 4. It may beaccepted at alternate five-yearly surveys for tailshaftsdescribed in [4.5.2] provided that:

• they are fitted with oil lubricated bearings and approvedoil sealing glands

• the shaft and its fittings are not exposed to corrosion

• the design details are approved

• the clearances of the aft bearing are found to be in order

• the oil and the oil sealing arrangements prove effective

• lubricating oil analyses are carried out regularly at inter-vals not exceeding six months and oil consumption isrecorded at the same intervals.

4.4.4 Tailshaft Monitoring System (MON-SHAFT)Where, in addition to the conditions stated in [4.5.3] formodified survey, the additional class notation MON-SHAFTis assigned, the tailshaft need not be withdrawn at both thecomplete and modified survey provided that all conditionmonitoring data is found to be within permissible limits andthe remaining requirements for the respective surveys arecomplied with.

4.4.5 Other propulsion systemsDriving components serving the same purpose as thetailshaft in other propulsion systems, such as directionalpropellers, vertical axis propellers, water jet units, dynamicpositioning systems and thruster assisted mooring systems,are to be submitted to periodical surveys at intervals notexceeding five years.

4.5 Boiler survey

4.5.1 Boilers and thermal oil heaters are to be surveyedtwice in every five-year period. The periodicity of the boilersurvey is two years and six months (2,5 years), but with amaximum interval between successive examinations notexceeding three years. Consideration may be given at thediscretion of RINA to any special circumstances justifyingan extension of these intervals


Pt A, Ch 2, Sec 2

4.5.2 For yachts of eight years of age and over fitted withone single boiler supplying steam for main propulsion, theinterval between two boiler surveys may be specially con-sidered.

4.5.3 Boilers are also submitted to an external inspectionas a part of the intermediate survey of machinery.

4.6 Links between anniversary dates and annual surveys, intermediate surveys and class renewal surveys

4.6.1 The link between the anniversary dates, the classrenewal survey and the intermediate surveys is given in Fig1.

Figure 1 : Links between anniversary date and annual, intermediate and class renewal surveys

5 Occasional surveys

5.1 General

5.1.1 An occasional survey is any survey which is not aperiodical survey. The survey may be defined as an occa-sional survey of hull, machinery, boilers, etc., depending onthe part of the yacht concerned. Where defects are found,the Surveyor may extend the scope of the survey as deemednecessary.

5.1.2 Occasional surveys are carried out at the time of, forexample:• damage or suspected damage• repair or renewal work• alterations or conversion• quality system audits• postponement of surveys or recommendations.

• updating of classification documents (e.g. change of theOwner, flag or name of the yacht)

5.2 Damage and repair surveys

5.2.1 In the event of damage which affects or may affectthe class of the yacht, the Owner is to apply to RINA for asurvey. Such application is to be made as soon as possibleto enable the Surveyor to ascertain the extent of the damageand necessary repairs, if any.

5.2.2 All repairs to hull, machinery and equipment whichmay be required in order for a yacht to retain its class are tobe to the satisfaction of the Surveyor.

During repairs or maintenance work, the Owner is toarrange so that any damage, defects or non-compliancewith the rule requirements are reported to the Surveyor dur-ing his survey.

5.2.3 Damages and partial or temporary repairs consid-ered acceptable by the Surveyor for a limited period of timeare the subject of an appropriate recommendation.

5.2.4 Damages or repairs required by the Surveyor to bere-examined after a certain period of time are the subject ofan appropriate recommendation.

5.3 Conversions, alterations and repairs

5.3.1 Conversions, alterations or repairs of/to structuresand arrangements affecting the class are to be carried out inaccordance with the requirements of RINA and to its satis-faction. Where necessary, documentation is to be submittedto RINA and/or made available to the attending Surveyor.

5.3.2 Materials and equipment used for conversions, alter-ations or repairs are generally to meet the requirements ofthe Rules for new yachts built under survey; see Sec 1,[2.1.6].

5.4 Quality System audits

5.4.1 RINA reserves the right to carry out occasional sur-veys in order to conduct audits either as deemed necessaryin pursuance of its internal Quality System or as required byexternal organisations (e.g. flag Administrations).

5.4.2 These surveys may also be attended by auditorsexternal and relevant scope of these surveys is determinedby RINA.

6 Change of ownership

6.1 General

6.1.1 In the case of change of ownership, the yacht retainsits current class provided that:

• RINA is informed of the change sufficiently in advanceto carry out any survey deemed appropriate,

• the new Owner signs the appropriate request, involvingacceptance of RINA's general conditions and Rules.This request covers inter alia the condition of the yachtwhen changing ownership.

Note 1: The yacht's class is maintained without prejudice to thoseprovisions in the Rules which are to be enforced in cases likely tocause suspension or withdrawal of the class such as particular dam-ages or repairs to the yacht of which RINA has not been advised bythe former or, as the case may be, new Owner.

Note 2: No information whatsoever related to the class of the yachtwill be provided or confirmed to any third party, unless the appro-priate request for information is duly completed and signed by theparty making the request and the authorization of the currentOwner is obtained.

7.1.1 A yacht put out of commission may be subject tospecific requirements for maintenance of class, provided

that the Owner notifies RINA of the fact. Surveys for mainte-nance of class of a laid up yachts will be specially consid-ered by RINA.


Pt A, Ch 2, Sec 3

SECTION 3 SUSPENSION AND WITHDRAWAL OF CLASS

1 General

1.1 Discontinuance of class

1.1.1 The class may be discontinued either temporarily orpermanently. In the former case it is referred to as "suspen-sion" of class, in the latter case as "withdrawal" of class. Inboth these cases, the class is invalidated in all respects.

1.2 Suspension of class

1.2.1 The class may be suspended either automatically orfollowing the decision of RINA. In any event, the yacht willbe considered as not retaining its class from the date of sus-pension until the date when class is reinstated.

1.2.2 The class is automatically suspended when one ormore of the following circumstances occur:

• when a yacht is not operated in compliance with therule requirements, such as in cases of services or condi-tions not covered by the service notation, or trade out-side the navigation restrictions for which the class wasassigned

• when a yacht proceeds to sea with less freeboard thanthat assigned, or has the freeboard marks placed on thesides in a position higher than that assigned, or, in casesof yachts where freeboards are not assigned, the draughtis greater than that assigned

• when the Owner fails to inform RINA in order to submitthe yacht to a survey after defects or damages affectingthe class have been detected

• when repairs, alterations or conversions affecting theclass are carried out either without requesting theattendance of RINA or not to the satisfaction of the Sur-veyor. For voyage repairs, reference is to be made toSec 2.

Suspension of class with respect to the above cases willremain in effect until such time as the cause giving rise tosuspension has been removed. Moreover, RINA may requireany additional surveys deemed necessary taking intoaccount the condition of the yacht and the cause of the sus-pension.

1.2.3 In addition, the class is automatically suspended:

• when the class renewal survey has not been completedby its limit date or within the time granted for the com-pletion of the survey, unless the yacht is under attend-

ance by the Surveyors with a view to completion priorto resuming trading

• when the intermediate surveys has not been carried outby the end of the corresponding survey time window(see Sec 2).

Suspension of class with respect to the above cases willremain in effect until such time as the class is reinstatedonce the due items and/or surveys have been dealt with.Intermediate and class renewal surveys will be creditedfrom their original limit dates.

1.2.4 In addition to the circumstances for which automaticsuspension may apply, the class of a yacht may also be sus-pended following the decision of RINA:

a) when a recommendation is not dealt with within thetime limit specified, unless it is postponed before thelimit date by agreement with RINA;

b) When the owner sells the yacht and he does not informRINA

c) when one or more surveys are not held by their limitdates or the dates stipulated by RINA, also taking intoaccount any extensions granted in accordance with theprovisions of Part A

d) when, due to reported defects, RINA considers that ayacht is not entitled to retain its class even on a tempo-rary basis (pending necessary repairs or renewals, etc.)

e) in other circumstances which RINA will consider ontheir merits (e.g. in the event of non-payment of fees orwhere the Owner fails to subject the yacht to the occa-sional survey).

Suspension of class decided by RINA takes effect from thedate when the conditions for suspension of class are metand will remain in effect until such time as the class is rein-stated once the due items and/or surveys have been dealtwith.

1.2.5 Yachts laid-up in accordance with the requirementsindicated in Sec 2, [7.1.1] prior to surveys coming dueneed not be suspended when surveys addressed abovebecome overdue.

1.2.6 However, yachts which are laid-up after being sus-pended as a result of surveys going overdue, remain sus-pended until the overdue surveys are completed.

1.3 Withdrawal of class

1.3.1 RINA will withdraw the class of a yacht in the fol-lowing cases:• at the request of the Owner• when the causes that have given rise to a suspension

currently in effect have not been removed within oneyear after due notification of suspension to the Owner.


Pt A, Ch 2, Sec 3

However, RINA may withdraw the class of the yachtbefore the end of such period where it deems it appro-priate. A longer suspension may be granted at RINA'sdiscretion when the yacht is not trading as in cases oflay-up, awaiting disposition in the case of a casualty orattendance for reinstatement.

• when the yacht is reported as a constructive total loss• when the yacht is lost• when the yacht is reported scrapped.

Withdrawal of class takes effect from the date on which thecircumstances causing such withdrawal occur.

1.4 Suspension and withdrawal

1.4.1 When the suspension and/or the withdrawal of classof a yacht comes into effect, RINA will:• forward the Owner written notice• notify the flag Administration (if due)

• make the information available to the Underwriters, attheir request.

1.5 Suspension/withdrawal of additional class notations

1.5.1 If the survey requirements related to maintenance ofadditional class notations are not complied with, the sus-pension or withdrawal may be limited to the notations con-cerned.

1.5.2 The suspension or withdrawal of an additional classnotation generally does not affect the class.

APPENDIX 1 THICKNESS MEASUREMENTS

1 General

1.1 Aim of the Appendix

1.1.1 Thickness measurements are a major part of surveysto be carried out for the maintenance of class, and the anal-ysis of these measurements is a prominent factor in thedetermination and extent of the repairs and renewals of theyacht's structure.

1.1.2 The Appendix is intended to provide Owners, com-panies performing thickness measurements and RINA's Sur-veyors with a uniform means with a view to fulfilling Rulerequirements for thickness measurements. In particular, itwill enable all the above-mentioned parties to carry out:

• the planning and preparation

• the determination of extent and location, and

• the analysis of the thickness measurements in coopera-tion.

1.2 Scope of the Appendix

1.2.1 Separate Articles below provide the following infor-mation:

• references to rule requirements and some additionalinformation on the extent of the thickness measure-ments to be performed during surveys according torelated surveys (see [2])

2 Rule requirements for the extent of measurements

2.1 General

2.1.1 For the maintenance of class, thickness measure-ments may be required during intermediate and classrenewal surveys.

Tab 1 gives the references to the requirements for minimumthickness measurements indicated in Chapter 3 related tothe different types of surveys.

Some additional explanations are also given about thewording used in these Rules as well as the general princi-ples of the required thickness measurements during classrenewal surveys.

Table 1 : Reference to Rule requirements related to thickness measurements

2.2 Class renewal survey

2.2.1 The thickness measurements required by these Rulesconsist of:

• systematic thickness measurements, i.e. measurementsof different parts of the structure in order to assess theoverall and local strength of the yacht;

• measurements of suspect areas as defined in Sec 2,[2.1.11];

• additional measurements on areas determined asaffected by substantial corrosion as defined in Sec 2,[2.1.12].

3 Number and locations of measure-ments

3.1 General

3.1.1 Considering the extent of thickness measurements asrequired by these Rules and indicated in [2] above, thelocations of the points to be measured are given here for themost important items of the structure. Thus the number ofpoints can be estimated.

3.2 Locations of points

3.2.1 Tab 2 provides explanations and/or interpretationsfor the application of those requirements indicated in theseRules which refer to both systematic thickness measure-ments related to the calculation of global hull girderstrength and specific measurements.

Figures are also given to facilitate the explanations and/orinterpretations given in the table. These figures show typicalarrangements of yachts.

Due to the various designs of the other yacht types, figuresare not given to cover all the different cases. However, the

4 Acceptance criteria for thickness measurements

4.1 General

4.1.1 Acceptance criteria stipulate limits of wastage whichare to be taken into account for reinforcements, repairs orrenewals of metallic structure. These limits are generallyexpressed for each structural item as a maximum percent-age of acceptable wastage (W). When the maximum per-centage of wastage is indicated, the minimum acceptable

thickness (tmin) is that resulting from applying this percent-age to the rule thickness (trule), according to the followingformula:

However, when the rule thickness is not available, theasbuilt thickness can be used.

Only for criteria related to an item (see [4.3.3] b), RINAmay establish a list of renewal thicknesses taylored to thedifferent structural items. In such a case these thicknessesare used in lieu of the minimum thicknesses calculatedfrom the percentage of wastage.

4.1.2 In cases where the yacht has some structural ele-ments with reduced wear margins (e.g. due to yacht conver-sion, increase of draught), the minimum acceptablethickness for these elements is to be calculated with refer-ence to the rule scantlings without taking account of anyreduction originally agreed.

4.1.3 Decisions on steel renewals are taken by the attend-ing Surveyor applying the criteria given in this Article andbased on his judgment and the actual condition of theyacht.

Should advice be needed to support his decision, the Sur-veyor may refer to the relevant technical office of RINA.

Section A-A


Pt A, Ch 2, App 1

4.2 Criteria

4.2.1 The acceptance criteria for the minimum thicknessesare divided into:• criteria on local and, where applicable, global strength,

given in [4.3]• criteria on buckling strength, given in [4.4]• criteria on pitting, given in [4.5].

4.2.2 Each measured structural item is to be checkedagainst the following criteria, as far as applicable. Whereany of the criteria are not met, reinforcements, repairs andrenewals are to be carried out as appropriate.

4.3 Local and global strength criteria

4.3.1 For the evaluation of the yacht longitudinal strength,it is a prerequisite that fillet welding between longitudinalmembers and deck, side and bottom plating is maintainedeffective so as to keep continuity of hull structures.

4.3.2 Each structural item to be assessed is illustrated in atypical transverse section (see Fig 5).These structural items are also listed in a table ( Tab 5)grouped according to their position and contribution to thelocal or global strength of the yacht.

4.3.3 Each structural item is to be assessed according tofour different criteria which vary with regard to the domainunder which it is considered, namely:

a) an isolated area, which is meant as a part of a singlestructural item. This criterion takes into considerationvery local aspects such as grooving of a plate or web, orlocal severe corrosion; however, it is not to be used forpitting for which separate criteria are considered (see[4.5])

b) an item, which is meant as an individual element suchas a plate, a stiffener, a web, etc. This criterion takes intoconsideration the average condition of the item, whichis assessed by determining its average thickness usingthe various measurements taken on the same item

c) a group of items, which is meant as a set of elements ofthe same nature (plates, longitudinals, girders) contrib-uting either to the longitudinal global strength of theyacht in a given zone or to the global strength of otherprimary transverse elements not contributing to theyacht longitudinal strength, e. g. bulkheads, web frames

d) a zone, which is meant as all and only longitudinal ele-ments contributing to the longitudinal strength of the

yacht; in this regard, the three main zones are defined asdeck zone, neutral axis zone and bottom zone. This cri-terion takes into consideration the average condition ofall groups of items belonging to the same zone.

4.3.4 The assessment of the thickness measurements is tobe performed using the values given in the tables for eachstructural element with regard to the criteria defined above,in the following order:

a) assessment of isolated areas (column 1 in the tables). Ifthe criterion is not met, the wasted part of the item is tobe dealt with as necessary.

b) assessment of items (column 2 in the tables). If the crite-rion is not met, the item is to be dealt with as necessaryin the measured areas as far as the average condition ofthe item concerned is satisfactory. In cases where someitems are renewed, the average thicknesses of theseitems to be considered in the next step are the newthicknesses.

c) assessment of groups of items (column 3 in the tables). Ifthe criterion is not met, a sufficient number of elementsare to be renewed in order to obtain an increased aver-age thickness satisfying the considered criterion of thegroup (generally the elements to be renewed are thosemost wasted). As an example, for the assessment of thegroup "deck plates" all deck plates are measured and anaverage thickness of each of them is estimated. Then theaverage of all these values is to satisfy the criteria givenfor this group.

d) assessment of zones (column 4 in the tables). In princi-ple, the criterion of the zone is met when all groups ofitems belonging to the zone meet their own criteria (seec) above). However, a greater diminution than thosegiven in column 3 may be accepted for one group ofitems if, considering the other groups of items belongingto the same zone, the overall diminution of the zonedoes not exceed the criterion given for it in column 4.

Example: The deck zone consists of two groups of items:

• deck plating, which has an average diminution of 12%(criterion 10%)

• deck longitudinals, which has an average diminution of4% (criterion 10%)

Even though the deck plating group exceeds its acceptancecriterion, the average diminution of the zone, which can bevery roughly estimated at 8%, is acceptable and thus thedeck plating group can be accepted as it is.

4.4 Buckling strength criterion

4.4.1 This criterion is applicable to yachts having a lengthgreater than 120 metres.

In addition to the evaluation of structural elements accord-ing to [4.3] above, the structural items contributing to the

longitudinal strength of the yacht, such as deck and bottomplating, deck and bottom girders, etc., are also to beassessed with regard to their buckling strength. The valuesshown in Tab 3 are not to be exceeded.

Note 1: The minimum thickness will be specially considered for

yachts built with excess hull girder section modulus.

4.5 Pitting

4.5.1 The maximum acceptable depth for isolated pits is35% of the as-built thickness.

4.5.2 For areas with different pitting intensity, the intensitydiagrams shown in Fig 4 are to be used to identify the per-centage of affected areas.

For areas having a pitting intensity of 50% or more, themaximum acceptable average depth of pits is 20% of the as-built thickness. For intermediate values between isolatedpits and 50% of affected area, the interpolation between35% and 20% is made according to Tab 4.

4.5.3 In addition, the thickness outside the pits in the areaconsidered is to be assessed according to [4.3] and [4.4]above.Note 1: Application of filler material (plastic or epoxy compounds)is recommended as a means to stop or reduce the corrosion proc-ess, but it is not considered an acceptable repair for pitting exceed-ing the maximum allowable wastage limits. Welding repairs maybe accepted when performed in accordance with proceduresagreed with RINA.

The specific requirementsfor class renewal surveys related to additional class nota-tions assigned to yachts are addressed in Chapter 4, respec-tively.

1.1.2 The class renewal survey is to include sufficientlyextensive examination and checks to show that the struc-tures, main and auxiliary machinery, systems, equipmentand various arrangements of the yacht are in satisfactorycondition or restored to such condition as to allow the yachtto operate for the new period of class to be assigned, pro-vided that the yacht is properly maintained and other sur-veys for maintenance of class are duly carried out duringthis period.

The examinations of the hull are to be supplemented bythickness measurements and testing as deemed necessary,to ensure that the structural integrity remains effective andsufficient to discover substantial corrosion, significantdeformation, fractures, damages or other structural deterio-ration.

1.1.3 The Owner is to provide the necessary facilities toenable this class renewal survey. The conditions for surveyas detailed in Ch 2, Sec 2, [2.4] to Ch 2, Sec 2, [2.6] are tobe met.

2 Hull and hull equipment

2.1 Bottom survey

2.1.1 The class renewal survey is to include a bottom sur-vey as laid down in Sec 3.

2.2 Decks and equipment

2.2.1 Decks are to be examined, particular attention beinggiven to the areas where stress concentration or increasedcorrosion are likely to develop, such as discontinuities ofstructure. Deck erections such as deckhouses and super-structures are to be examined.

The sheathing of wood-sheathed steel decks may beremoved, at the Surveyor's discretion, in the case of doubtas to the condition of plating underneath. At class renewalsurveys of yachts more than 15 years of age, portions ofwood sheating, or other coverings on steel deck are to beremoved, as considered necessary by the Surveyor, in order

to ascertain the condition of the plating underneath; thesame for non steel yachts.

Due attention is to be given to the examination in way ofend and side openings and related shell and inner doors.

2.2.2 The survey of hull equipment is to cover the follow-ing points:

• windlass and chain stoppers, with disassembly asdeemed necessary to verify the condition of the equip-ment and control and safety devices, hawse pipes;

• steering arrangements, including steering gear, controland indication devices, operational tests and disassem-bly as deemed necessary; in the case of chain and rodgears, chains, rods, sheaves, pins and rollers are to beexamined for wear;

• connection of masts and standing rigging to the hullstructure as well as condition of structure underneath.

2.2.3 Piping systems outside tanks and compartments areto be visually examined and pressure tested as necessary, asper the requirements laid down for the class renewal surveyof machinery and systems; see [3.5].

2.2.4 Automatic air pipe heads are to be completely exam-ined (both internally and externally ) as indicated in Tab 4.For designs where the inner parts cannot be properlyinspected from outside, this is to include removal of thehead from the air pipe. Particular attention is to be paid tothe condition of the zinc coating in heads constructed fromgalvanised steel.

2.2.5 The anchors and chain cables are to be ranged andexamined, and the required complement and condition ver-ified. The chain locker, holdfasts, hawse pipes and chainstoppers are to examined. At class renewal surveys of yachtsmore than 5 years of age, chain cables are to gauged andrenewed in cases where their mean diameter is worn belowthe limits allowed (12%).

2.2.6 In yachts constructed of composite materials, partic-ular attention shall be paid to the joints between deck andhull and between deck and superstructure. The structure inway of the bolted attachment of fittings including davit,hinges for shell doors, guardrails stanchions, windlass, shaftbrackets, mooring bitts, etc is to be examined.

2.3 Dry compartments

2.3.1 Tweendecks, cofferdams, pipe tunnels and ductkeels, void spaces and other dry compartments which areintegral to the hull structure are to be internally examined,ascertaining the condition of the structure, bilges and drainwells, sounding, venting, pumping and drainage arrange-ments. For this purpose, the removal of interiors (linings,ceiling/cabin sole), insulations and in general coverings,


Pt A, Ch 3, Sec 2

shall have an extension as deemed necessary by the Sur-veyor (taking into consideration the age of the yacht, too).

2.3.2 Machinery and boiler spaces, pump rooms and otherspaces containing machinery are to be internally examined,ascertaining the condition of the structure. Particular atten-tion is to be given to tank tops, shell plating in way of tanktops, brackets connecting side shell frames and tank tops,and bulkheads in way of tank tops and bilge wells. Particu-lar attention is also to be given to the sea suctions, sea watercooling pipes and overboard discharge valves and theirconnections to the shell plating. Where wastage is evidentor suspected, thickness measurements are to be carried out,and renewals or repairs effected when wastage exceedsallowable limits.

Piping systems inside these spaces are to be dealt withaccording to [3.5].

2.3.3 Chain lockers are to be internally cleared, cleanedand examined, while the anchor chains are ranged asrequired for in [2.2.5]. The pumping arrangement of thechain lockers is to be tested.

2.4 Tanks

2.4.1 The type and number of tanks to be internally exam-ined at each class renewal survey are detailed in Tab 1,according to the age of the yacht.

This internal examination is to ascertain the condition of thestructure, bilges and drain wells, sounding, venting, pump-ing and drainage arrangements, including piping systemsand their fittings. Due attention is to be given to plating ordouble plates below the lower end of sounding and suctionpipes.

Where wastage is evident or suspected, thickness measure-ments are to be carried out, and renewals or repairs effectedwhen wastage exceeds allowable limits.

Where the inner surface of the tanks is covered with cementor other compositions, the removal of coverings may be

waived provided they are examined, found sound andadhering satisfactorily to the steel structures.Note 1: For examination of independent (non-structural) tanks,refer to [3.5.9].

Note 2: Due attention is also to be given to fuel oil piping passingthrough ballast tanks, which is to be pressure tested when the yachtis more than 10 years old.

2.4.2 For salt water ballast spaces other than double bot-tom tanks, integral sanitary tanks and bilges where a protec-tive coating is found to be in poor condition, as defined inCh 2, Sec 2, [2.2.14] and is not renewed, where soft coat-ing has been applied or where a protective coating hasnever been applied, i.e. neither at the time of constructionnor thereafter, maintenance of class is to be subject to thespaces in question being internally examined at annual sur-veys. RINA may consider waiving such internal examina-tion at annual surveys of tanks protected with soft coating,whose size is 12 m3 or less.For salt water ballast double bottom tanks, where suchbreakdown of coating is found and is not renewed, wheresoft coating has been applied or where a protective coatinghas never been applied, i.e.neither at the time of construc-tion nor thereafter, maintenance of class may be subject tothe tanks in question being internally examined at annualsurveys.

2.4.3 Boundaries of double bottom, ballast, peak andother tanks are to be tested by a head sufficient to give themaximum pressure that can be experienced in service.Thanks may be tested afloat provided that their internalexamination is also carried afloat.

2.4.4 Boundaries of fuel oil, lube oil and fresh water tanksare to be tested with a head of liquid to the maximum fillinglevel of the tank. Tank testing of fuel oil, lube oil and freshwater tanks may be specially considered based on a satis-factory external examination of the tank boundaries, and aconfirmation from the Master stating that the pressure test-ing has been carried out according to the requirements withsatisfactory results.

SECTION 3 BOTTOM SURVEY

1 General

1.1

1.1.1 The bottom survey may be carried out in dry condi-tion, such as in dry dock or on a slipway, or through an in-water survey.

The conditions for acceptance of a bottom in-water surveyin lieu of a bottom survey in dry condition are laid down inCh 2, Sec 2, [4.4.4] and [3].

2 Bottom survey in dry condition

2.1 General requirements

2.1.1 When a yacht is in dry condition, it is to be placedon blocks of sufficient height and with the necessary stagingto permit the examination of elements such as shell platingincluding bottom and bow plating, stern frame and rudder,sea chests and valves, propeller, etc.

2.1.2 The outer shell is to be visually examined for exces-sive corrosion, or deterioration due to chafing or contactwith the ground or for any undue deformation or buckling.

Due attention is to be given to the end structures (stem andsternframe).

In particular, considering the different constructions' mate-rial following to be examined:

• metallic yachts: connection between the bilge strakesand the bilge keels.

• GRP yachts: condition of gealcoat (presence of crack-ing, blistering and other damages);

• wooden yachts: condition of caulking and rivets.

Significant plate unevenness or other deterioration whichdoes not necessitate immediate repairs is to be recorded.

.

2.1.3 Sea chests and their gratings, sea connections andoverboard discharge valves and cocks and their fasteningsto the hull or sea chests are to be examined. Valves andcocks need not be opened up more than once in a classrenewal survey period unless considered necessary by theSurveyor.

2.1.4 Visible parts of the propeller(s), stern bush(es), pro-peller shaft boss, brackets and tightness system(s) are to beexamined. The clearances of the propeller shaft(s) (or weardown gauge) are to be checked and recorded. For controlla-ble pitch propellers, the Surveyor is to be satisfied with thefastenings and tightness of hub and blade sealing. Visible

parts of other propulsion systems and propellers for steeringpurposes are also to be examined.Dismantling is to be carried out, if considered necessary,notably where leakages are detected.

3.1 General

3.1.1 An in-water survey may normally be carried out ifthe yacht has been granted the additional class notationINWATERSURVEY (Y)as defined in Ch 1, Sec 2, [6.6.1].Upon application by the Owner and in special circum-stances, RINA may also authorise such bottom inwater sur-vey for yachts not assigned with the additional classnotation INWATERSURVEY (Y).

3.1.2 The bottom in-water survey is to provide the infor-mation normally obtained from a bottom survey carried outin dry condition, and the scope of the in-water survey is thesame as detailed in [2.1], so far as practicable. Proposalsfor inwater surveys are to be submitted in advance of thesurvey so that satisfactory arrangements can be agreed onwith RINA.In principle, no outstanding recommendations are to existrequiring repair work to be carried out to the underwaterpart of the shell plating, the rudder, the propeller or the pro-peller shaft, unless RINA is satisfied that such repairs maybe carried out while the yacht is afloat.

3.1.3 The in-water survey is to be carried out with theyacht at a light draught in sheltered water and preferablywith weak tidal streams and currents. The in-water visibilityis to be good and the hull below the waterline is to be suffi-ciently clean to permit meaningful examination.RINA is to be satisfied with the methods of localization ofthe divers on the plating, which should make use where


Pt A, Ch 3, Sec 3

necessary of permanent markings on the plating at selectedpoints.

The equipment and the procedure for observing and report-ing the survey are to be discussed with the parties involvedprior to the in-water survey, and suitable time is to beallowed to permit the diving company to test all equipmentbeforehand.

3.1.4 The in-water survey is to be carried out by one ormore professional divers in the presence of a Surveyor. Thediver(s) is (are) to be employed by a firm agreed by RINA.For the agreement of such firms, refer to Ch 2, Sec 2, [2.3].

3.1.5 The Surveyor is to be satisfied with the method ofpictorial representation, and good two-way communicationbetween the Surveyor and the divers is to be provided.

3.1.6 If the in-water survey reveals damage or deteriora-tion that requires early attention, the Surveyor may requirethe yacht to be drydocked in order for a detailed survey tobe undertaken and the necessary repairs carried out.

3.1.7 Special attention is to be given to the hull in way ofunderwater fittings, such as stabilizers.

1.1.1 The requirements of this Annex apply to yachts withwooden hull.

The applicable requirements of Pt A are generally to becomplied with, taking account of the modifications andadditions specified in [3.1], [3.2], [ 3.3] and [3.4], as faras the frequency and the technical requirements relevant tosurveys are concerned.


2.1

2.1.1 The requirements of Pt A, Ch 2, Sec 2 of the Rulesare to be fulfilled; however, in the case of yachts more than10 years old, the frequency of the bottom survey is subjectto special consideration.

3 Periodical hull surveys


3.1.1 The yacht is to be inspected, as far as practicable atthe time of the survey, in order to verify that the hull and itsequipment are in a satisfactory and efficient condition andthat no significant unapproved modifications or alterationshave been made which could affect the class and/or thesafety of the yacht concerned.

The checks to be performed to this end are to include, interalia, the following items:

a) the outside shell above the waterline, with particularattention to the butts of shell and sheerstrake planking;

b) weather decks, with particular attention to the butts ofwaterways, inner waterways and planking;

c) hatchways (coamings, shifting beams, fore and aft cov-ers, etc.), other deck openings (with closing appliances,ventilator coamings, etc.) and bulwarks;

d) deck fittings and appliances, such as bollards, fairleads,guard-rails, ladders, etc.;

e) masts and rigging, and sails, if any (with iron fittings,standing and running rigging, etc.), including lightningconductors;

f) wire equipment - towline, hawsers and warps, andstream-anchor wire (or chain), if required;

g) the windlass and chain-cables as far as accessible;

h) the equipment of anchors and chain-cables;

i) main and auxiliary steering arrangements, with particu-lar attention to the rod and chain gear, if fitted;

j) freeboard marks;

k) the deck outfit, tools and gear;

l) enclosed spaces, as far as accessible at the time of thesurvey.

For the purpose of the above, survey operations other thanthose mentioned above, but deemed equivalent by theRINA Surveyor in terms of the characteristics and generalcondition of the yacht concerned, may also be carried out.

3.1.2 In addition to the provisions given in [3.1.1], allenclosed spaces are to be examined by the RINA Surveyorin charge to verify their condition.

In the course of the inspection, the following hull structuralmembers are to be examined, in particular: beams, deck,girders, pillars, knees, frames (after removal of air-coursesand ceiling at the discretion of the Surveyor), breasthooks,deadwoods, keelsons, inner planking (beam shelves,clamps, thick strakes of ceiling, sparring, etc.), with particu-lar attention to the examination of the butts of all longitudi-nal members.

Fastenings are also to be examined to verify their generalcondition.

The Surveyor may require a check of the condition of thestructure by means of a more extensive specific examina-tion, such as removal of portions of the inner planking andtesting of timbers by axe, chisel or other suitable tool.

3.2 Bottom surveys

3.2.1 The survey is to consist of the following checks:

a) Check of the condition of the outside planking and itscaulking by means of suitable tests, as deemed neces-sary by the attending Surveyor, on each side of theyacht, amidships and at the ends, in the vicinity of thewaterline and near to the keel, with local removal of anymetal sheathing, as necessary. When evidence of deteri-oration is found in the outside planking and its caulking,additional tests are to be made as necessary to deter-mine the extent of renewal of planking or re-caulkingrequired. If it is found that general re-caulking of theoutside planking is necessary, the metal sheathing, ifany, is to be entirely removed and the outside plankingis to be thoroughly cleaned. At the discretion of theRINA Surveyor, after re-caulking the metal sheathing is


Pt A, Ch 3, App 3

to be renewed either entirely or in the deterioratedareas.

b) Check of the condition of keel, deadwood, stem, stern-post, rudder and associated pintles and gudgeons andall sea openings.

c) Examination of sea connections, of the attachments ofvalves to the yacht shell and of gratings; where thevalves fitted to the yacht shell are of cast iron, they areto be opened for examination at every Docking Survey;where they are of ductile material, they are to beopened for examination at intervals not exceeding 4years.

d) Measurement of clearances in the rudder gudgeons andthe wear down in the rudder carrier bearing and stern-bush.

Moreover, in the case of a Docking Survey held concur-rently with a First Classification or Special Survey, all thosechecks are to be performed which are required for such sur-veys and which can only be carried out when the yacht is indrydock or on a slipway.

3.3 Class renewal survey No. 1

3.3.3 Any surfaces in contact with rust are to be wellscraped and the outside surface of the shell planking, fromthe light waterline to the covering boards, is to be wellcleaned and scraped.

3.3.4 The condition of fastenings is to be checked and, ifconsidered necessary by the RINA Surveyor, a sufficientnumber of fastenings is to be drawn to enable their condi-tion and that of the adjacent timber to be thoroughlychecked. In this connection, particular attention is to begiven to iron fastenings, especially in way of the waterline,and fastenings made of copper or yellow metal are to betested, as far as practicable, and renewed when found to bebroken or excessively worn.

3.3.5 The sheerstrake planking is to be tested by drawing asufficient number of treenails, or by boring if no treenailsare fitted; the holes resulting from the latter are subse-quently to be closed by treenails or bolts.

3.3.6 If the keel and centre keelson are connected by ironfastenings, a sufficient number of these fastenings is to bedrawn to check their condition; where this is impracticable,additional fastenings, as required by the Surveyor, are to befitted in the connection of keel with centre keelson, of stemand stern-post with aprons and inner stern-posts, and alsoin the connection of other main structural members.

3.3.7 Particular attention is to be given to the examinationof breasthooks, frames, beams (particularly at their ends),knees, hawse timbers, knight heads, transoms and all foreand aft structural members.

3.3.8 If visual examination or testing by sounding and bor-ing reveals rot or decay due to woodworm, the affectedareas and adjacent timbers are to be closely inspected and,if necessary for the purpose, additional parts are to beremoved in order to decide the extent of renewal required.

3.3.9 Bulwarks, bulwark stays, guard-rails and similar fit-tings, and superstructures in general are to be examined inorder to check their condition.

3.3.10 Anchors and chain-cables are to be examined inaccordance with the requirements in Pt A.
