A vessel has a deadweight carrying capacity of 10,500 tons. Fuel, water, and stores require 1500 tons. The cubic capacity is 500,000 cubic feet. Which cargo will put her full and down?

Correct Answer: Option D — Rolls of barbed wire, SF 55.5

A vessel is full and down when both deadweight capacity (10,500 - 1,500 = 9,000 tons available) and bale cubic capacity (500,000 cu ft) are fully utilized simultaneously. Calculating cargo stowage factors against available spaces identifies rolls of barbed wire (SF 55.5) as achieving this exact balance.
