Safety & Environmental Protection (Deck) USCG Question #2259 (Set 69)

Your vessel's drafts are FWD 24'-09", AFT 27'-01". Use the information in Section 1, the blue pages, of the Stability Data Reference Book to determine the final drafts if 122 tons are discharged 76 feet aft of amidships, 128 tons are discharged 54 feet forward of amidships, and 68 tons of fuel is pumped 48 feet aft.

Official USCG Answer & Rule Citation

Correct Answer: Option D — FWD 24'-04", AFT 26'-08"

Applying principles from stability reference data, calculating parallel sinkage and trim changes from multiple discharged and shifted weights yields final drafts of FWD 24'-04" and AFT 26'-08". Proper accounting of longitudinal centers of gravity and moment to trim ensures accurate vessel draft determination.
