Official USCG Answer & Rule Citation

Correct Answer: Option C — 2.05 feet

With initial drafts of FWD 08'-11.5" and AFT 15'-11.5" plus table ST-0138 loading, calculate the final displacement and permeability. Entering the SS AMERICAN MARINER subdivision standards in the Stability Data Reference Book determines the minimum required GM of 2.05 feet.
