Question 2641Deck Safety70% to pass
Your vessel's drafts are: FWD 16'-08", AFT 17'-06"; and the KG is 23.8 feet. Use the selected stability curves in the blue pages of the Stability Data Reference Book to determine the remaining righting arm at 60° inclination if the center of gravity is 1.7 feet off the centerline.
AI Explanation
The correct answer is B) 2.1 feet.
To determine the remaining righting arm at 60° 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 find the corresponding stability curve and use it to read the righting arm at 60° inclination. With the center of gravity being 1.7 feet off the centerline, the remaining righting arm is 2.1 feet.
The other options are incorrect because they do not accurately reflect the righting arm at 60° inclination based on the provided information. Option A (1.8 feet) is too low, while options C (3.0 feet) and D (3.8 feet) are too high.
