Summary

A U.S. vessel must carry an official logbook unless it is sailing from a U.S. port to a Canadian port. A logbook is required when the ship is going from a U.S. port to any foreign port, or when the ship is at least 100 gross tons (or an approved alternate tonnage) and is traveling between a U.S. Atlantic port and a U.S. Pacific port. The ship’s captain must make or have entries in the logbook about many crew and ship events. These include convictions and punishments of crew, offenses meant to be prosecuted or forfeited (with a note that the charge was read and the crew member’s reply), punishments given on board, a short statement about each crew member’s conduct and qualifications (or a note declining to give an opinion), illnesses and injuries and their treatment, deaths (with cause and required details), births (sex and parents’ names), marriages (names and ages), crew who leave the ship (place, time, how, and why), wages and deductions for a crew member who dies during the voyage, sale of a deceased crew member’s property (items and amounts), reports of marine accidents made right away when possible, and failures to follow ballast water rules (including when a safety exemption caused the failure), recorded right away when possible.
