Question 2652Deck Safety70% to pass
Your vessel's drafts are: FWD 24'-06", AFT 25'-04"; and the KG is 17.8 feet. Use the selected stability curves in the blue pages of the Stability Data Reference Book to determine the remaining righting arm at 75° inclination if the center of gravity is 2.5 feet off the centerline.
AI Explanation
The correct answer is C) 5.4 feet.
To determine the remaining righting arm at 75° inclination, we need to use the stability curves in the blue pages of the Stability Data Reference Book. Given the vessel's drafts and the center of gravity being 2.5 feet off the centerline, we can locate the appropriate stability curve and read the righting arm value at 75° inclination, which is 5.4 feet.
The other options are incorrect because they do not match the value obtained from the stability curves. Option A (2.5 feet) is the distance of the center of gravity from the centerline, not the righting arm. Options B (3.3 feet) and D (9.7 feet) are not the correct values based on the stability curves.
