Question 2660 Deck Safety

The correct answer is D) 18,240 foot-tons. To calculate the righting moment when the vessel is inclined to 30 degrees, we need to use the information provided in the Stability Data Reference Book, Section 1 (the blue pages). Based on the vessel's drafts (FWD 14'-11", AFT 16'-01") and KG (24.4 feet), we can find the righting moment at 30 degrees of heel from the appropriate table or graph in the reference book. The correct value given in the answer choices is 18,240 foot-tons. The other answer choices are incorrect because they do not match the value provided in the Stability Data Reference Book for the given vessel characteristics and heel angle.
