The SS AMERICAN MARINER is ready to load the cargo listed in table ST-0125 below. There is already 4236 tons of cargo on board with a KG of 27.2 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 A — KG 26.9 feet

Finding final combined KG requires compounding existing cargo moments with new cargo moments from table ST-0125. Summing initial moments (4236 tons x 27.2 ft) and new cargo moments, then dividing by total combined weight, determines the final vessel cargo KG of 26.9 feet.
