Question 2650 Deck Safety

The correct answer is A) 0.7 foot. To determine the remaining righting arm at 30° inclination, you need to use the stability curves in the blue pages of the Stability Data Reference Book. Given the vessel's drafts and KG, you can locate the appropriate stability curve and find the righting arm at 30° inclination. With the center of gravity being 1.9 feet off the centerline, the righting arm at 30° inclination is 0.7 foot, as indicated by the stability curve. The other options are incorrect because they do not match the value obtained from the stability curve for the given vessel characteristics and center of gravity offset.
