You have 520 tons of below deck tonnage including liquid mud. Your existing deck cargo is 160 tons with a VCG above the deck of 2.7 feet. What is the maximum cargo tonnage you are permitted to load? See illustration D036DG below.

Correct Answer: Option A — 84 tons

Determining total allowable cargo per 46 CFR Subchapter W stability curves in illustration D036DG for 520 tons below deck (including liquid mud) and 160 tons of deck cargo at a 2.7-foot VCG permits a total maximum cargo loading of 84 tons beyond existing weights.
