Question 1978 Deck Safety

The correct answer is A) volume in cubic feet. Gross tonnage is a measure of the overall internal volume of a vessel, not its weight or displacement. It is calculated based on the total enclosed volume of the ship, including the hull, superstructure, and other enclosed spaces. This volumetric measurement reflects the overall size and capacity of the vessel, rather than its weight or draft. The other options are incorrect because they do not accurately represent what gross tonnage indicates. Option B refers to the total weight of the vessel, including cargo, which is not what gross tonnage measures. Options C and D relate to the vessel's physical dimensions or displacement, which are separate measurements from gross tonnage.
