The SS AMERICAN MARINER has drafts of: FWD 28'-00", AFT 29'-00". Use the white pages of the Stability Data Reference Book to determine the drafts if you ballast the forepeak with 81.05 tons of seawater.

Official USCG Answer & Rule Citation

Correct Answer: Option B — FWD 28'-07.3", AFT 28'-07.8"

Introducing 81.05 tons of seawater into the forepeak tank changes the vessel trim based on longitudinal center of flotation data, resulting in new calculated drafts of FWD 28'-07.3" and AFT 28'-07.8".
