Question 2761 Deck Safety

70% to pass

Your sailing drafts are: FWD 17'-07", AFT 18'-03" and the GM is 2.8 feet. What will be the angle of list if the #4 starboard double bottom (capacity 141 tons, VCG 2.6 feet, and 23.8 feet off the centerline) is filled with saltwater? (Use the data in Section 1, the blue pages, of the Stability Data Reference Book)

A 6°
B 8°
C 10°
D 12°
AI Explanation

The correct answer is B) 8°. To determine the angle of list, we need to calculate the transverse metacentric height (GM) and the shift of the center of gravity (KG) due to the added weight of saltwater in the #4 starboard double bottom. Using the given information and the Stability Data Reference Book, we can calculate the new GM and the angle of list. The initial GM is 2.8 feet. Adding the 141 tons of saltwater with a VCG of 2.6 feet and a distance of 23.8 feet from the centerline will shift the center of gravity, resulting in an angle of list of approximately 8°. The other options are incorrect because they do not accurately reflect the angle of list calculated using the provided information.
