You are on a supply run to an offshore drilling rig. You are carrying the load show in table ST-0039 below. What is the height above the main deck of the center of gravity of the cargo?

Correct Answer: Option D — 1.38 feet

Determining cargo center of gravity on an offshore supply vessel involves summing vertical moments of individual deck items and dividing by total cargo weight. Per stability principles outlined in 46 CFR, the aggregate moment calculation yields a final height of 1.38 feet above the main deck.
