Safety & Environmental Protection (Deck) USCG Question #2573 (Set 78)

Your vessel's drafts are: FWD 16'-08", AFT 17'-06"; and the KG is 23.8 feet. Use the selected stability curves in the blue pages of the Stability Data Reference Book to determine the remaining righting arm at 60° inclination if the center of gravity is 1.7 feet off the centerline.

Official USCG Answer & Rule Citation

Correct Answer: Option B — 2.1 feet

Accounting for transverse center of gravity displacement off the centerline, the net righting arm at 60 degrees inclination is reduced by the eccentricity factor GG' sin(theta), resulting in a remaining righting arm of 2.1 feet.
