Safety & Environmental Protection (Deck) USCG Question #2291 (Set 70)

The SS AMERICAN MARINER has drafts of: FWD 18'-07", AFT 23'-03". Use the white pages of the Stability Data Reference Book to determine the drafts if you ballast the forepeak with 92 tons of seawater.

Official USCG Answer & Rule Citation

Correct Answer: Option A — FWD 19'-04.9", AFT 22'-08.7"

Adding 92 tons of ballast to the forepeak tank alters the vessel's trim by shifting the center of gravity forward. Utilizing hydrostatic particulars and moment tables from the Stability Data Reference Book yields the resulting drafts of FWD 19'-04.9" and AFT 22'-08.7".
