Question 2621Deck Safety70% to pass
Your vessel's drafts are: FWD 27'-06", AFT 28'-02"; and the KG is 23.1 feet. Use the selected stability curves in the blue pages of the Stability Data Reference Book to determine the righting arm at 60° inclination.
AI Explanation
The correct answer is B) 1.8 feet.
The righting arm at 60° inclination can be determined using the selected stability curves in the blue pages of the Stability Data Reference Book. With the given drafts of 27'-06" forward and 28'-02" aft, and a KG of 23.1 feet, the stability curves can be used to find the righting arm at 60° inclination, which is 1.8 feet.
The other options are incorrect because 0.9 foot (A) is too low, 2.7 feet (C) is too high, and 4.5 feet (D) is significantly higher than the correct value of 1.8 feet.
