What is one of the few exemptions to the safe manning requirement?

• A. Desertion; the vessel can sail short if caused by a desertion, and the master determines that the vessel is sufficiently manned to remain seaworthy
• B. Medical leave
• C. Port restrictions
• D. Crew training day off

Answer: (A)

The concept being tested is that there is only a narrow, formal exception to the minimum safe manning rules: if crew desertion reduces the number of people on board. In that situation, the master may still sail with a reduced crew, but only if the remaining crew can operate the vessel safely, maintain proper watchkeeping, and handle emergencies, so the ship stays seaworthy. This is why desertion is the best answer: it is a recognized, specific condition under which temporary reductions in crew can be approved.

Other scenarios like medical leave, port restrictions, or a crew training day off aren’t recognized exemptions to safe manning, because they don’t guarantee the vessel can be operated safely with fewer hands, and they don’t provide an approved basis for sailing short-handed.
