Safety & Environmental Protection (Deck) USCG Question #2251 (Set 69)

A vessel's drafts are FWD 20'-08", AFT 20'-10". Use the information in Section 1, the blue pages, of the Stability Data Reference Book to determine the final drafts if 195 tons of cargo are discharged 76 feet forward of amidships.

Official USCG Answer & Rule Citation

Correct Answer: Option B — FWD 19'-09", AFT 21'-01"

Discharging 195 tons forward decreases mean draft and alters trim by creating a relative aft-end sinkage, resulting in final drafts of FWD 19'-09" and AFT 21'-01" as determined via stability tables.
