Ship's record is a document that is kept on board a ship to record the details of its voyage. It is also known as a logbook or LOG. The logbook is usually divided into sections, such as the deck LOG, engine LOG, and radio LOG. The logbook is used to record the ship's position, speed, weather conditions, and any other events that occur during the voyage. The logbook is also used to record the crew's activities, such as maintenance and repairs. The logbook is an important document for the ship's captain, as it provides evidence of the ship's activities and can be used in legal proceedings. The term 'LOG' is three letters long, while 'logb' is four letters long.
