Your vessel's drafts are: FWD 27'-06", AFT 28'-02"; and the KG is 23.1 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 2.4 feet off the centerline.

Correct Answer: Option C — 0.5 foot

Extract the uncorrected righting arm ($GZ$) from the cross-curves of stability at 60° for the given displacement and KG. Apply the transverse correction by subtracting the off-center component ($GG' \sin\theta$) where $GG' = 2.4$ feet, resulting in a remaining righting arm of 0.5 foot per stability data reference principles.
