Standard practice to make factual entries in deck log book - Collection of evidence on board ship

The Deck Log Book is an important document and serves as necessary evidence in case of any Accidents and Casualties. It must contain Factual Entries with Time in each entry. Logbooks, also referred to as Captain's Logs or Deck Logs, consist of chronological entries documenting the daily activities of a merchant ship. A clear and accurate record of the activities of the ship must be kept, as the Logbook will form the main part of the collection of evidence in case of any incidents. Deck Log Book must be retained on board indefinitely.

Entries to be made in the Deck Log Book should cover, but not be limited to the following information:
Deck Log Books are documents of primary importance, forming as they do a record of the progress of a voyage, the details of loading and discharging cargo, and the narrative of all events affecting the management and running of the vessel. It is the Master's responsibility to ensure that the Log Book is maintained in a legible, factual, and punctual manner.

In the event of official investigations, courts of inquiry, and settlement of disputes with Shippers, Receivers, Charterers, and others, the Deck Log Book production is required, and how this important document has been kept has considerable bearing upon the favorable outcome of the case. The Master is to personally scrutinize the Log Book, and sign each day's page to verify the entries therein with the Chief Officer. Besides, rough logs and cargo logs can also be used as evidence in case of disputes, and they must be accurately compiled.
