Question 2637 Deck Safety

The correct answer is A) 0.7 foot. The righting arm at 15° inclination can be determined by using the selected stability curves in the blue pages of the Stability Data Reference Book, given the vessel's drafts (FWD 18'-09" and AFT 20'-05") and the KG of 23.8 feet. Based on the provided information, the righting arm at 15° inclination is 0.7 foot, which makes option A the correct answer. The other options are incorrect because they do not accurately reflect the righting arm value at the specified 15° inclination, as determined from the stability curves using the given vessel characteristics.
