You have 300 tons of below deck tonnage including liquid mud. Your existing deck cargo is 180 tons with a VCG above the deck of 1.9 feet. What is the maximum additional cargo tonnage you are permitted to load? See illustration D036DG below.

Correct Answer: Option C — 162 tons

Evaluating vessel stability limits per 46 CFR Subchapter W using diagram D036DG, 300 tons of below-deck tonnage and 180 tons of deck cargo at a 1.9-foot VCG permit an additional cargo loading of 162 tons without violating maximum allowable vertical center of gravity thresholds.
