You have 360 tons of below deck tonnage and 210 tons of above deck cargo on board. You must load 100 tons of liquid mud below deck. How much more deck cargo can you load? See illustration D036DG below.

Correct Answer: Option B — 65 tons

Applying stability limitations from illustration D036DG with 360 tons below deck, 210 tons of existing deck cargo, and 100 tons of newly loaded liquid mud below deck restricts the vessel's vertical moment balance, permitting exactly 65 tons of additional deck cargo.
