Question 2764 Deck General

The correct answer is C) Master of the vessel. The responsibility for maintaining the Official Logbook on voyages between the Atlantic and Pacific coasts of the United States rests with the Master of the vessel. This is because the Master, also known as the Captain, is the highest-ranking officer on the ship and is ultimately responsible for the vessel's operations, including the maintenance of the official logbook. The logbook is a legal document that records key events, navigational information, and other details of the voyage, and the Master is required to ensure its proper upkeep. The other options are incorrect because the Chief Mate, Purser, and Deck Officer of the watch are not the primary responsible parties for maintaining the Official Logbook. They may have some duties related to the logbook, but the overall responsibility lies with the Master of the vessel.
