Which is NOT a required entry in the ship's Official Logbook?

Correct Answer: Option D — Dry docking of the vessel

46 U.S.C. 11301 mandates specific entries for the Official Logbook, including medical treatments, deaths, and cargo gear inspections. Dry docking is a major maintenance event documented in the vessel's continuous survey records and maintenance logs, but it is not a statutory requirement for the Official Logbook entry.
