Safety & Environmental Protection (Deck) USCG Question #2283 (Set 70)

The SS AMERICAN MARINER has drafts of: FWD 22'-03", AFT 24'-00". Use the white pages of the Stability Data Reference Book to determine the drafts if you ballast the forepeak with 100.7 tons of seawater.

Official USCG Answer & Rule Citation

Correct Answer: Option C — FWD 23'-01.0", AFT 23'-05.7"

Forepeak ballasting of 100.7 tons creates a substantial forward moment. Applying stability book trim correction tables to initial drafts of FWD 22'-03" and AFT 24'-00" produces final drafts of FWD 23'-01.0" and AFT 23'-05.7".
