Log Book Details
|Every ship that travels on the oceans keeps a log book. The log book is
used by the crew as a help in running the ship and to keep track of where the ship has
been and what it has been doing. Different ships will write different details in the log
book, depending on what they do. We are writing a book, making a TV series and developing
this web site - so we try to remember all the fun and interesting bits, as well as the
basic navigation data.
|With the basic data you can follow where we go and learn about navigation
||Which day the log entry was made
||Which part of the voyage we're on. It says "towards" because we
can never be sure if we're going to get there...
||Usually it will be 12.00, sometimes we haven't started or already arrived
then so it might be different when we're starting or finishing a trip.
||We use a compass to steer by. The course will be a number between 0º and
360º. What does it mean?
||At sea, one always measures distance and speed using Nautical Miles and
||How far we have sailed on this trip
||A position means where something is. In our case it is where on the earth
(ocean) we are. If you find a good map you should be able to put a little mark where we
have been. The Latitude (North or South of the equator) and Longitude (East or West of the
Greenwich meridian) is usually written at the edges of a map.
||The wind direction and wind speed in Knots.
||Barometric pressure in millibars. Knowing if the pressure is going up or
down helps us decide how much sail we can set and what weather changes to expect.
