Safety & Environmental Protection (Deck) USCG Question #2674 (Set 81)

The SS AMERICAN MARINER has on board 5480 tons of cargo with an LCG-FP of 272.20 feet. See table ST-0105 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 C — LCG-FP 265.1 feet

Longitudinal center of gravity calculations utilize vessel stability reference tables to sum moments divided by total cargo weight. Following standard Hydrostatic principles outlined in Title 46 CFR, the distributed moments in table ST-0105 yield a final LCG from the forward perpendicular of 265.1 feet.
