You are on a supply run to an offshore drilling rig. You are carrying the load show in table ST-0004 below. What is the height above the main deck of the center of gravity of the cargo?

Correct Answer: Option B — 4.2 feet

Evaluating the specific cargo distribution listed in table ST-0004 requires summation of vertical moments about the baseline. Dividing the accumulated vertical moments by the total cargo weight yields a combined center of gravity height of 4.2 feet above the main deck.
