Your vessel's drafts are: FWD 17'-07", AFT 16'-09"; and the KG is 21.5 feet. Use the selected stability curves in the blue pages of the Stability Data Reference Book to determine the remaining righting arm at 30° inclination if the center of gravity is 0.9 foot off the centerline.
Official USCG Answer & Rule Citation
Correct Answer: Option B — 2.8 feet
Extract the uncorrected righting arm at 30° inclination using the provided draft and KG parameters. Subtract the transverse center of gravity correction ($0.9 \times \sin 30°$) to yield the remaining righting arm of 2.8 feet.
