Question 588 Deck General

The correct answer is D) Rolls of barbed wire, SF 55.5. The key factor here is the cubic capacity of the vessel, which is given as 500,000 cubic feet. To fully load the vessel, you need to choose the cargo that will completely fill the available cubic capacity. Rolls of barbed wire, with a stowage factor (SF) of 55.5, will have the highest cubic capacity of the options provided. The other cargo options, such as bundles of rubber (SF 140.2) or barrels of tallow (SF 66.8), would not fully utilize the 500,000 cubic feet of space available, leaving unused capacity. The other answer choices are incorrect because they either have a higher stowage factor, meaning they would not fully utilize the available cubic capacity, or a lower stowage factor, meaning they would not put the vessel "full and down."
