Safety & Environmental Protection (Deck) USCG Question #2663 (Set 80)

The SS AMERICAN MARINER has on board 4850 tons of cargo with an LCG-FP of 279.84 feet. See table ST-0159 below for the distribution of the cargo to be loaded. Use the white pages of The Stability Data Reference Book to determine the final LCG-FP of the cargo.

Official USCG Answer & Rule Citation

Correct Answer: Option D — LCG-FP 270.6 feet

Stability table ST-0159 provides specific longitudinal arms for cargo distribution. Multiplying each compartment's tonnage by its respective arm distance, combining with initial vessel moments, and dividing by total weight correctly calculates the final LCG-FP as 270.6 feet.
