The SS AMERICAN MARINER has on board 5480 tons of cargo with an LCG-FP of 274.46 feet. See table ST-0191 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 B — LCG-FP 272.87 feet
Longitudinal stability assessment requires calculating cargo weight moments using standard vessel data tables. For table ST-0191, summing individual compartment weights and their respective LCG distances establishes the resultant transverse and longitudinal center, resulting in 272.87 feet.
