Question 2763 Deck Safety

70% to pass

Your vessel's drafts are: FWD 27'-09", AFT 28'-03"; and the KG is 22.4 feet. Use the selected stability curves in the blue pages of the Stability Data Reference Book to determine the angle of list if the center of gravity is shifted 1.6 feet off the centerline.

A 16°
B 20°
C 24°
D 30°
AI Explanation

The correct answer is C) 24°. To determine the angle of list, we can use the stability curves in the blue pages of the Stability Data Reference Book. Given the vessel's drafts and KG, we can find the appropriate stability curve and then determine the angle of list based on the center of gravity shift of 1.6 feet off the centerline. The other options are incorrect because 16° would be the angle of list for a smaller center of gravity shift, 20° and 30° do not match the angle of list indicated by the stability curves for the provided information.
