Question 2888 Deck General

The correct answer is C) Boatswain's stores. The reasoning behind this is that boatswain's stores, which are spaces used for the storage of supplies, equipment, and other materials necessary for the operation and maintenance of the vessel, are deducted from the gross tonnage to arrive at the net tonnage. This is in accordance with the regulations and guidelines governing the measurement of vessel tonnage. The other options, such as passenger spaces (A) and companions and booby hatches (B), are not deducted from the gross tonnage to derive the net tonnage. They are considered part of the vessel's overall volume and are included in the calculation of gross tonnage.
