Question 2979 Deck General

The correct answer is D) All of the above. The Master has the authority to require the crew to work when needed for maneuvering, shifting berth, mooring and unmooring (A), performing work necessary for the safety of the vessel, its passengers, crew or cargo (B), and performing fire, lifeboat or other drills in port or at sea (C). These are all essential duties that the Master may call upon the crew to perform as needed to ensure the safe operation of the vessel. The other answer choices are incorrect because they do not encompass the full scope of the Master's authority over the crew's work assignments.
