Your vessel (185 GT) is on a voyage between New York and San Francisco. Which statement is TRUE?

Correct Answer: Option C — An Official Logbook must be maintained.

Under 46 U.S.C. § 11301, an Official Logbook is required for vessels of at least 100 gross tons on a voyage between a port in the United States and another port in the United States. Since the vessel is 185 GT, it meets the tonnage threshold for this mandatory record-keeping requirement.
