The SS AMERICAN MARINER is ready to load the cargo listed in table ST-0132 below. There is already 3175 tons of cargo on board with a KG of 25.8 feet. Use the white pages of the Stability Data Reference Book to determine the final KG of all the cargo after loading is completed.

Official USCG Answer & Rule Citation

Correct Answer: Option A — KG 26.8 feet

Determining final cargo KG involves taking the initial weight and moment, adding the specific cargo weights and vertical centers from table ST-0132, and computing the weighted average. The resulting final vertical center of gravity is 26.8 feet, satisfying standard stability assessment procedures for merchant vessels.
