Question 2649 Deck Safety

70% to pass

Your vessel's drafts are: FWD 21'-04", AFT 21'-08"; and the KG is 20.6 feet. Use the selected stability curves in the blue pages of the Stability Data Reference Book to determine the remaining righting arm at 45° inclination if the center of gravity is 1.2 feet off the centerline.

A 3.8 feet
B 4.4 feet
C 5.2 feet
D 5.6 feet
AI Explanation

The correct answer is B) 4.4 feet. To determine the remaining righting arm at 45° 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 45° inclination. With the center of gravity being 1.2 feet off the centerline, the righting arm will be reduced, and the correct answer is 4.4 feet. The other options are incorrect because they do not accurately reflect the reduction in righting arm due to the off-center center of gravity.
