Official USCG Answer & Rule Citation

Correct Answer: Option C — 2.21 feet

Entering table ST-0041 and utilizing the designated initial drafts of 09'-10" forward and 15'-08" aft within the Stability Data Reference Book provides the necessary stability limits. Cross-referencing deadweight factors yields a minimum required metacentric height (GM) of 2.21 feet for one-compartment survival capability.
