Safety & Environmental Protection (Deck) USCG Question #2286 (Set 70)

The SS AMERICAN MARINER has drafts of: FWD 28'-00", AFT 30'-04". Use the white pages of the Stability Data Reference Book to determine the drafts if you ballast the forepeak with 110.8 tons of seawater.

Official USCG Answer & Rule Citation

Correct Answer: Option A — FWD 28'-09.8", AFT 29' 10.4"

Utilizing ship-specific hydrostatic tables for the SS AMERICAN MARINER, adding 110.8 tons of seawater to the forepeak changes the trim forward and aft proportionately, resulting in updated operational drafts of FWD 28'-09.8" and AFT 29' 10.4".
