Title 46 - Shipping
In addition to prescribing watch requirements, 46 U.S.C. 8104 sets limitations on the working hours of licensed individuals and crew members, prescribes certain rest periods, and prohibits unnecessary work on Sundays and certain holidays when the vessel is in a safe harbor. It is the responsibility of the master or person in charge to ensure that these limitations are met. However, under 46 U.S.C. 8104(f), the master or other licensed individual can require any part of the crew to work when, in his or her judgment, they are needed for: (a) Maneuvering, shifting berth, mooring, unmooring; (b) Performing work necessary for the safety of the vessel, or the vessel's passengers, crew, or cargo; (c) Saving of life on board another vessel in jeopardy; or, (d) Performing fire, lifeboat, or other drills in port or at sea.
