70% to pass

Your vessel's drafts are: FWD 24'-07", AFT 25'-09"; and the KG is 23.2 feet. What is the righting moment when the vessel is inclined to 45°? (Use the reference material in Section 1, the blue pages, of the Stability Data Reference Book)

A 27,008 foot-tons
B 29,778 foot-tons
C 32,428 foot-tons
D 34,663 foot-tons
AI Explanation

The correct answer is D) 34,663 foot-tons. To calculate the righting moment at 45 degrees of inclination, we need to use the formula provided in Section 1 (the blue pages) of the Stability Data Reference Book: Righting Moment = Displacement × GZ, where GZ is the righting arm at 45 degrees. Given the vessel's drafts and KG, we can determine the necessary values from the reference tables and calculate the righting moment. The correct righting moment at 45 degrees of inclination is 34,663 foot-tons. The other answer choices are incorrect because they do not accurately reflect the righting moment based on the provided information and the formula from the reference material.
