Question 2633Deck Safety70% to pass
Your vessel's drafts are: FWD 24'-06", AFT 25'-04"; and the KG is 22.2 feet. Use the selected stability curves in the blue pages of the Stability Data Reference Book to determine the righting arm at 20° inclination.
AI Explanation
The correct answer is C) 1.4 feet.
To determine the righting arm at 20° inclination, you need to use the stability curves provided in the blue pages of the Stability Data Reference Book. Given the vessel's drafts (FWD 24'-06", AFT 25'-04") and the KG of 22.2 feet, you can locate the appropriate stability curve and read the righting arm at 20° inclination, which is 1.4 feet.
The other answer choices are incorrect because they do not match the value provided in the stability curves for the given vessel characteristics.
