Your vessel's drafts are: FWD 27'-06", AFT 28'-02"; and the KG is 21.3 feet. Use the selected stability curves in the blue pages of the Stability Data Reference Book to determine the righting arm at 15° inclination.

A 0.3 foot
B 1.3 feet
C 1.5 feet
D 1.8 feet
AI Explanation

The correct answer is C) 1.5 feet. To determine the righting arm at 15° inclination, you need to use the stability curves provided in the blue pages of the Stability Data Reference Book. Based on the given vessel drafts (FWD 27'-06", AFT 28'-02") and the KG of 21.3 feet, the stability curve corresponding to these parameters will show the righting arm at 15° inclination, which is 1.5 feet. The other answer choices are incorrect because they do not match the value obtained from the stability curves for the given vessel characteristics.
