Question 2659 Deck Safety

The correct answer is A) 10,656 foot-tons. To calculate the righting moment at 15° of inclination, we need to use the formula provided in Section 1 (the blue pages) of the Stability Data Reference Book: Righting Moment = W x GZ, where W is the vessel's displacement and GZ is the righting arm at the given angle of inclination. Given the vessel's drafts and KG, we can calculate the righting arm (GZ) at 15° of inclination using the tables and information provided in the reference book. Multiplying the vessel's displacement (W) by the calculated GZ at 15° yields the correct righting moment of 10,656 foot-tons. The other answer choices are incorrect because they do not match the righting moment calculated using the provided information and the Stability Data Reference Book.
