A well-kept ships logbook should serve as an accurate narrative, permitting anyone to subsequently plot the cruise again from the information supplied.
The entries in the ships log can be followed in reverse over the course run, rather in the way that Theseus found his way out of the labyrinth. All the details used in laying the course must be entered: compass course (the one asked for and the one actually followed), the log readings, strength and direction of the wind, sea conditions.
All changes should also be noted: going about, changes of sail, changes in the weather, fixes taken (and how they were made), along with any ships met. Nothing must be judged insignificant
The ships log must be kept scrupulously up to date, even when dead reckonings are not expected to be made. If there is an accident, then the ships log can be invaluable as evidence of what actually happened.
If the boat is equipped with GPS or other electronic position finder, the log must still be kept up to date and the position noted regularly. This can then serve as the starting point for a dead reckoning in case of instrument malfunction or failure.
The Glenans Manual of Sailing
At the beginning of each cruise, enter the crew list, departure port and date.
Each morning, enter the tides and draw the days tidal curve. Take the first hourly barometer read-ing. Make your passage plans for the day and write them down in a separate Navigators Notebook, listing the charts required. If a night sail is in-volved, list the characteristics of any relevant lights in the Notebook.
Every time something happens, or when some-thing changes, or once an hour, enter details of a Position Fix and a Sailing Observation (leaving or entering a harbour, changing course, taking a reef, spotted a Navy boat, something has broken, the Skippers started drinking). Details of that whale on the port side, flying fish, and interesting birdlife can be entered under Nature Sightings.
Record the weather forecast regularly using the Met Eireann Sea Area chart and the UK Met Map provided in this Log Book. Photocopy those pages as many times as needed and take them on your cruise.
A well-kept personal log book is useful when preparing for the ISA or RYA Coastal Skipper or Yachtmaster practical examination at sea. Use this log book to record your sea miles. When sailing as crew, ask your skipper to sign and date the entries after each cruise.

The descriptive scale mariners and meteorologists use to describe the speed of the wind was first standardised by an Irishman in the British Royal Navy, Admiral Sir Francis Beaufort. Born in County Louth in 1774, Beaufort was of French Huguenot origin and joined the Navy as a midshipman at the age of 14. His father, a clergyman, purchased the boys commission into the Navy, as was the custom at the time. Beaufort served a long and distinguished career at sea, rising to the rank of Admiral, achieving the post of Hydrographer to the Royal navy and was awarded a knighthood. He devised a 13 point scale of wind force which was officially adopted by the Navy in 1805. He chose to define his wind scale in common terms used everyday by seamen. As his yardstick, he chose a fully rigged man o war, the largest type of battleship then in service afloat. He described his scale using the effect winds would have on such a ship and the sails it might carry. Thus, a Gale Force 8 was a wind strength in which a well conditioned man o war might carry triple reefs and courses. Force 0 was a calm and Force 2 was a slight breeze, terms readily understood by the sailors of his day. Beaufort retired from the Navy to his familys lands in Louth, where he died in 1857. In the early 1900s, an all-iron Navy had little use for terms describing the effect of wind on sailing ships. The scale was revised and wind strengths described in terms of their effect on the open sea surface. For the benefit of landlubbers, a second set of descriptive terms was devised, using loose bits of paper, flags, twigs and umbrellas to describe the strength and the effect of wind inland.

Each Sea Area Forecast issued by Met Eireann contains the following standard elements: Meteorological or General Situation: A description of the meteorological situation over Ireland at the stated time and of adjacent weather systems, e.g. depressions, anticyclones or frontal troughs, which are expected to influence the forecast areas during the following 24 hours. A general forecast follows giving wind, weather and visibility for Irish coastal waters and the Irish Sea. Terms used to describe Weather Fine dry, mainly sunny day, clear after dark Fair dry, good sunny or clear spells (no more than 3 - 5 oktas of medium or low cloud or 6 - 8 oktas of high cloud). Cloudy 6 - 8 oktas of low or medium cloud Mist visibility restricted by water droplets Haze visibility restricted by dust or smoke Terms used to describe Visibility Good more than 5 nautical miles (9 km) Moderate 2 - 5 nautical miles (4 - 9 km) Poor 1,100 yards to 2 nautical miles Fog less than 1,100 yards (1000 metres) Coastal Reports taken from Malin Head, Dublin Airport, Rosslare, Roches Point Automatic, Valentia and Belmullet and new moored ocean buoys include these details: wind direction on the 16 point compass, speed in knots weather visibility in miles and yards pressure in hectoPascals (millibars) pressure tendency, which describes change in pressure
over the preceding 3 hours according to this scale: 0.0 - 0.4 hPa steady 0.5 - 1.9 hPa rising or falling slowly 2.0 - 3.4 hPa rising or falling 3.5 - 5.9 hPa rising or falling rapidly 6.0 hPa + rising or falling very rapidly
Outlook includes a brief description for the 24 hour pe-riod following the period covered by the forecast. Gale Warnings are issued for Irish coastal waters, which are regarded as extending 30 miles out from the coast line, and the Irish Sea. Gale Beaufort Force 8 winds expected. Strong Gale Force 9 winds or frequent gusts of at least 52 knots expected. Storm Force Force 10 or frequent gusts of at least 61 knots expected. Violent Storm Force 11 or frequent gusts of at least 69 knots expected Hurricane Force winds greater than 64 knots Speed of movement of Pressure Systems is described as: slowly up to 15 knots steadily 15 to 25 knots rather quickly 25 to 35 knots rapidly 35 to 45 knots very rapidly greater than 45 knots Onset of gale force or stronger winds is described as: imminent within 6 hours soon between 6 and 12 hours later between 12 and 24 hours Swell Wave Heights are issued in the warnings section of the Sea Area Forecast, using the mariners convention whereby heavy swell means swell waves of 4 metres or higher. Sea State Wave Height in Metres Calm 0 - 0.1 Wavelets 0.1 - 0.5 Slight 0.5 - 1.25 Moderate 1.25 - 2.5 Rough 2.5 - 4 Very Rough 4 - 6 High 6 - 9 Very High 9 - 14 Phenomenal Over 15
