Question 2655 Deck Safety
70% to passYour vessel's drafts are: FWD 22'-04", AFT 23'-06"; and the KG is 22.4 feet. Use the selected stability curves in the blue pages of the Stability Data Reference Book to determine the righting arm at 19° inclination if the center of gravity is 1.3 feet off center.
The correct answer is A) 0.2 foot. To determine the righting arm at 19° inclination, you need to use the selected stability curves in the blue pages of the Stability Data Reference Book. Given the vessel's drafts and KG, you can locate the appropriate curve and read off the righting arm value at 19° inclination. Since the center of gravity is 1.3 feet off center, this will slightly affect the righting arm value, but the correct answer based on the information provided is 0.2 foot. The other answer choices are incorrect because they do not accurately reflect the righting arm value at 19° inclination for the given vessel characteristics and center of gravity offset.
