Your vessel's drafts are: FWD 15'-09", AFT 16'-08"; and the KG is 23.6 feet. Use the selected stability curves in the blue pages of the Stability Data Reference Book to determine the angle of list if the center of gravity is shifted 0.9 foot off the centerline.

Correct Answer: Option A — 15°

Evaluating the blue page stability curves in the Stability Data Reference Book for the given draft and a 23.6-foot KG, a transverse center of gravity shift of 0.9 feet corresponds to an intersecting righting arm curve value yielding a 15-degree list.
