Question 2664Deck Safety70% to pass
Your vessel's drafts are: FWD 24'-07", AFT 25'-09"; and the KG is 24.0 feet. What is the righting moment when the vessel is inclined to 15°? (Use the selected stability curves in Section 1, the blue pages, of the Stability Data Reference Book)
AI Explanation
The correct answer is B) 8,666 foot-tons.
To determine the righting moment when the vessel is inclined to 15 degrees, we need to use the stability curves provided in Section 1 (the blue pages) of the Stability Data Reference Book. Given the vessel's drafts (FWD 24'-07", AFT 25'-09") and KG (24.0 feet), we can locate the appropriate stability curve and read the righting moment at 15 degrees, which is 8,666 foot-tons.
The other options are incorrect because they do not match the value obtained from the stability curve. Option A (5,202 foot-tons) and Option C (10,876 foot-tons) are too low and too high, respectively, while Option D (11,424 foot-tons) is also incorrect.
