The maximum draft of the SS AMERICAN MARINER cannot exceed 30'-01" in order to cross a bar. The present drafts are: FWD 29'-04", AFT 30'-06". Use the white pages of the Stability Data Reference Book to determine the minimum amount of sea water to ballast the forepeak to achieve this condition.
Official USCG Answer & Rule Citation
Correct Answer: Option B — 100 tons
Achieving the maximum allowable draft of 30'-01" for bar clearance from initial drafts requires determining the differential trim using the stability data reference book, which dictates precisely 100 tons of forepeak ballast.
