LSV SOP 5.6 – Design & Manufacture of Surfcraft Policy

INDEX 5.6:POL:1 EFFECTIVE DATE: 01/10/2004

Design and Manufacture of Surfcraft Policy Purpose To outline requirements for the Design and Manufacture of Surfcraft Scope All operational levels of Life Saving Victoria Policy This Bulletin contains the following specifications. Specification No. 1 - Rescue Craft, Solid Foam/Fibreglass Construction Specification No. 2 - Surf Board Specification No. 3 - Single Ski Specification No. 4 - Double Ski Specification No. 5 - Junior (Nipper) Fibreglass Surf Board Specification No. 6 - Junior (Nipper) Foam Surf Board Specification No. 7 - "Long Board" Open 9 foot Division General 2.1 The specification for RESCUE CRAFT is mandatory to all Craft

purchased for SLSA use and is also applicable to any Craft donated as, or purchased as, "Rescue Craft".

2.2 Such Craft may be subject to inspection by the SLSA to ensure

the terms of these specifications are being observed. 2.3 Craft not complying with the correct specifications will not be

designated as Surf Rescue equipment. 2.4 UNDER NO CIRCUMSTANCES WILL CRAFT PURCHASED

UNDER ANY GOVERNMENT GRANT ASSISTANCE BE ALLOWED TO TAKE PART IN ANY COMPETITION ACTIVITY EXCEPTING INTERNAL CLUB COMPETITIONS AND



PATROL COMPETITIONS CONDUCTED AT BRANCH, STATE OR NATIONAL LEVEL.

2.5 Craft purchased as rescue boards, and not strictly to

specification (whether at the direction of the Club or by reasons of the builder) MUST be reported to SLSA and the relevant State Centre immediately.

Variations from Specifications 3.1 Provision is allowed in SLSA procedures for Craft to be

constructed outside the specification - for the purpose of improvement of design, performance or material evaluation.

3.2 HOWEVER, such permission can only be forthcoming from

SLSA and as a result of a detailed submission. 3.3 Submissions must contain all relevant information and drawings

etc., in support of the application. 3.4 THE OUTCOME OF THE APPLICATION MUST NOT

HOWEVER BE PRESUMED, AND NO DEVIATIONS FROM SPECIFICATION CAN BE UNDERTAKEN UNTIL PERMISSION HAS BEEN GIVEN IN WRITING BY THE SLSA.

3.5 SLSA permission to develop craft outside specification is no

guarantee of final approval and all such activity shall be at no expense to SLSA.

SLSA National Surf Craft Manufacturers Registration Scheme 4.1 Applicant to apply in writing to SLSA, outlining company name,

company principal, address, contact numbers, company background or profile, and craft to be manufactured (i.e. junior boards, single skis, etc). An initial (non-refundable) registration fee of $385 (includes GST) is to accompany the initial application.

4.2 Subsequent applications, from a registered manufacturer for

registration to manufacture additional types of surf craft, must be accompanied by a supplementary (non-refundable) registration fee of $110 (includes GST).

4.3 On receipt of the above application, applicant will be advised in

writing that they will be required to build one craft, of each type



for which registration is sought, for inspection by the National Surf Craft Officer (or nominee). The applicant will also be issued with a copy of current relevant SLSA specifications.

4.4 On advice from the Manufacturer that the craft moulds, (if

appropriate) and appropriate manufactured craft are ready for inspection, the National Surf Craft Officer (or nominee) will arrange an inspection to check that the appropriate standards are met.

4.5 Following the inspection, the manufacturer will be advised in

writing of the outcome of the Application for Registration. The outcome of the application cannot be assumed until written confirmation has been received by the manufacturer from SLSA.

4.6 If successful, an Official Agreement will then be forwarded to

the manufacturer for their signature. Manufacturers cannot manufacture or sell items purporting to comply with SLSA specifications until the agreement has been signed and returned by SLSA.

4.7 If registration is not approved, the Manufacturer will be notified

by the SLSA of the reasons and what action that should be taken in order that registration may be reconsidered.

4.8 The Manufacturer is then required (if successful) to purchase

from SLSA, Compliance labels ($2.20 each - includes GST) to be glassed under the surface of all craft (except junior foam surfboards) manufactured to SLSA specifications.

4.9 Compliance Labels are numbered and stamped with

Manufacturers name. The Manufacturer is also required to date the label with date of manufacture (month and year). Further, the manufacturer is required to keep an up-to-date record of all numbers in sequence, craft type, colour, finished weight, and name and address of purchaser of each craft.

4.10 Annual re-registration will occur on September 30 each year at

which time an agreement will be forwarded by SLSA to each manufacturer. A re-registration fee of $110 (non-refundable- includes GST) must accompany the agreement when returned to SLSA. If the agreement and fee is not received by SLSA in 30 days, the manufacturer’s agreement will become null and void. Should this occur, the manufacturer must again pay the $385 (includes GST) initial non-refundable registration fee and proceed through the original process in becoming a registered



manufacturer if they wish to become a SLSA Registered Manufacturer.

4.11 Manufacturers applying for annual re-registration may continue

to manufacture craft or sell items while the new agreement is being signed.

4.12 Penalties for non compliance with SLSA specifications (also see

Agreement):

- A letter from SLSA will be sent asking the manufacturer to explain their actions to SLSA in writing.

- A panel consisting of the SLSA Chief Executive Officer,

Director of Competition and the National Surf Craft Officer (or their nominee), will adjudicate on each non compliance matter separately and on its` merits, as required.

4.13 Manufacturers should be aware that an authorised SLSA

representative shall be entitled at all times during normal working hours to have necessary access to the premises of a manufacturer to inspect craft, moulds if appropriate, the manufacturing process and the Craft Manufacturing Register. This is necessary to ensure that craft, which have been manufactured or are in the course of manufacture comply with the conditions and specifications as outlined in this document and SLSA specifications for manufacturing of surf craft.

4.14 Manufacturers will be placed on the SLSA national mailing list

and will receive club mail in order to keep them abreast of current matters within SLSA.

Note: i) Craft built by Registered Manufacturers and not bearing the “SLSA Approved” sticker will not be permitted to participate in SLSA competitions/activity, with the exception of Junior (Nipper) Foam Surf Boards which must comply to Specification No. 6 of this Bulletin but may be subject to safety checks and compliance at all SLSA activities. ii) Craft not built by Registered Manufacturers and not bearing the “SLSA Approved” sticker will need to be scrutineered by a Surf Craft Inspector nominated by the National Surf Craft Officer with the manufacturer paying a fee as advised by the SLSA.



iii) The SLSA at all levels through carnival/activity organisers, reserves the right to scrutineer any or all equipment at any said activity. Purpose of the Specification These specifications refer to Craft used in SLSA competition/rescue and will be used by SLSA Officials to determine the eligibility, or otherwise, of competitor's craft. Any competitor, or club, who attempts to win a race by any other than honourable means may be disqualified. This includes the use of Craft not meeting the requirements of the appropriate SLSA specifications. Manufacturers have an obligation to SLSA to ensure that all craft manufactured comply with the appropriate specifications. Clubs/competitors have a responsibility to ensure craft remain within specification. When a change in basic design is contemplated, manufacturers shall first seek the advice of the National Surf Craft Officer or his/her nominee as assigned by Surf Life Saving Australia.
