Question

The SS AMERICAN MARINER is ready to load the cargo listed in table ST-0130 below.  There is already 4260 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.

Accepted Answer

Option D: KG 25.9 feet. Summing the vertical moments of pre-existing cargo and the specific cargo increment detailed in table ST-0130, then dividing by total cargo weight, accurately produces the final calculated vertical center of gravity of 25.9 feet.
