Which log includes a statement of the conduct, ability, and character of each crew member on the completion of a voyage?

Correct Answer: Option D — Official Logbook

Per 46 U.S.C. 11301, the Official Logbook is a legal document maintained by the Master. It must record the conduct, character, and ability of each crew member upon discharge or voyage completion, serving as a permanent record of service and disciplinary actions taken during the vessel's operation.
