You have 180 tons of below deck tonnage including liquid mud. Your existing deck cargo is 300 tons with a VCG above the deck of 3.0 feet. What is the maximum additional cargo tonnage you are permitted to load? See illustration D036DG below.

Correct Answer: Option C — 100 tons

Maximum additional deck cargo capacity is determined using stability booklet illustration D036DG by evaluating allowable vertical moments. With 180 tons below deck including mud and 300 tons existing deck cargo at 3.0 feet VCG, the vessel can accept 100 tons more.
