Your vessel's drafts are: FWD 19'-09", AFT 20'-09"; and the KG is 24.6 feet. Use the selected stability curves in the blue pages of the Stability Data Reference Book to determine the remaining righting arm at 15° inclination if the center of gravity is 0.5 foot off the centerline.

Correct Answer: Option A — 0.0 feet

Locate the righting arm at 15° inclination from the blue pages based on vessel drafts and KG. Subtract the transverse center of gravity correction ($0.5 \times \sin 15°$), which reduces the initial righting arm to zero feet, indicating neutral effective stability against further heel.
