The SS AMERICAN MARINER is ready to load the cargo listed in table ST-0050 below. . There is already 2865 tons of cargo on board with a KG of 27.8 feet. Use the white pages of the Stability Data Reference Book to determine the final KG of all the cargo after loading is completed.

Correct Answer: Option C — KG 28.5 feet

Determining combined center of gravity involves calculating total vertical moments by adding existing cargo moments to new cargo moments from table ST-0050. Dividing total cumulative moments by the final total weight yields the correct overall vertical center of gravity of 28.5 feet.
