The main function of a logbook is to provide a logical framework for the recording of navigational and related information. It should be sufficiently detailed to enable an estimated position to be plotted by reference to previous entries.
On a coastal passage entries will often be a combination of a regular hourly entry and those made at random times as events occur.
As a vessel goes further offshore an hourly entry will usually suffice, with a latitude and longitude noted in the logbook and plotted on the chart.
With a regular position logged and plotted you will be well placed to continue with confidence should your electronics fail.
The discipline of keeping a log will help you in many other ways:
• You will build up a better picture of the performance of your yacht in different conditions.
• Typical passage times.
• What weather trends to expect based on barometer readings.
• It helps break up the long night watches by providing a tired crew with a task.
• What places to come back to in future and which to avoid.
As well as being an essential navigational record a well kept logbook has the bonus of providing fascinating reading in later years, recording who sailed with you, where you went, the kind of weather you experienced, what wildlife was encountered, where that great little restaurant was etc. The more detail you include the more interesting it will become.
This logbook also provides you with a handy place to record useful names and addresses and has a handy season's summary so that mileages, engine hours etc. are easily recorded.
