Summary

A United States vessel must have an official logbook except when it is sailing from a U.S. port to a Canadian port. A logbook is required if the vessel is going from a U.S. port to any foreign port, or if the vessel is at least 100 gross tons (or an alternate tonnage measured under sections 14302 or 14502 as set by the Secretary under section 14104) and it is traveling between a U.S. Atlantic port and a U.S. Pacific port. The ship’s captain must write or cause to be written in the logbook many events about the crew and the ship. These include convictions, offenses meant to be prosecuted or fined (with notes showing the entry was read and the crew member’s reply as required by section 11502), punishments given on board, a short statement about each crew member’s conduct and qualifications (or a note that the captain won’t give an opinion), illnesses and injuries with treatment, deaths (with cause and the details required by section 10702), births (sex and parents), marriages (names and ages), any crew member who leaves the ship (place, time, how and why), wages due to a crew member who dies and total deductions, sales of a dead crew member’s property with prices, an immediate statement about any marine casualty when practicable, and an immediate statement about any failure to follow ballast water rules (including when a safety exemption caused the failure) as set by the Secretary.
