Question 2847 Deck General

The correct answer is D) Boatswain's stores. The boatswain's stores are deducted from the gross tonnage to derive the net tonnage. This is in accordance with the regulations governing the measurement of vessels for the purpose of determining tonnage and the issuance of a ship's certificate. The spaces occupied by the boatswain's stores, which are necessary for the operation and maintenance of the vessel, are not considered part of the cargo or passenger spaces and are therefore excluded from the gross tonnage calculation. The other options (A, B, and C) are not correct because passenger spaces, open structures, and galleys fitted with ranges or ovens are not deducted from the gross tonnage to derive the net tonnage.
