The SS AMERICAN MARINER has drafts of: FWD 29'-04", AFT 30'-06". Use the white pages of the Stability Data Reference Book to determine the drafts if you ballast the forepeak with 101.6 tons of seawater.

Official USCG Answer & Rule Citation

Correct Answer: Option B — FWD 30'-00.8", AFT 30'-01.0"

Adding 101.6 tons of seawater to the forepeak tank creates a forward trim moment. Utilizing the stability reference book hydrostatic curves for the SS AMERICAN MARINER, the resulting draft changes yield FWD 30'-00.8" and AFT 30'-01.0".
