You have 420 tons of below deck tonnage and 180 tons of above deck cargo on board. You must load 140 tons of liquid mud below deck. How much more deck cargo can you load? See illustration D036DG below.

Correct Answer: Option A — 60 tons

Analyzing allowable cargo additions using stability diagram D036DG ensures the vessel maintains positive initial stability and adequate freeboard. Incorporating 420 tons below deck, 180 tons existing deck cargo, and 140 tons of liquid mud limits additional deck cargo to 60 tons.
