The SS AMERICAN MARINER has on board 6048 tons of cargo with an LCG-FP of 270.89 feet. See table ST-0109 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 266.6 feet
Longitudinal weight-moment summation using table ST-0109 integrates initial cargo state with newly added distribution weights. Dividing the aggregate longitudinal moment by the updated total cargo weight produces the exact final LCG-FP position of 266.6 feet.
