Question 2645 Deck Safety

The correct answer is A) 0.6 foot. To determine the remaining righting arm at 30° inclination, we need to use the stability curves in the blue pages of the Stability Data Reference Book. Given the vessel's drafts and KG, we can locate the appropriate stability curve and read off the righting arm at 30° inclination. Since the center of gravity is 1.5 feet off the centerline, this will slightly reduce the righting arm compared to the centerline value. The other options are incorrect because they do not match the value obtained from the stability curves for the given vessel characteristics and off-center center of gravity.
