Question 2627 Deck Safety

The correct answer is B) 0.8 foot. To determine the available righting arm at 15° inclination, we need to use the information provided in the Stability Data Reference Book, Section 1 (the blue pages). Given the forward draft of 16'-06", the aft draft of 17'-04", and the GM of 2.6 feet, we can use the stability curves to find the righting arm at 15° inclination, which is 0.8 foot. The other options are incorrect because they do not match the value obtained from the stability curves in the reference book. Option A (0.4 foot) and Option C (1.2 feet) are too low and too high, respectively, while Option D (1.9 feet) is significantly higher than the correct value.
