Question 2755 Deck Safety

70% to pass

Your sailing drafts are: FWD 18'-03", AFT 19'-07" and the GM is 4.3 feet. What will be the angle of list if #2 starboard double bottom (capacity 78 tons, VCG 2.7 feet, and 24.5 feet off the centerline) is filled with saltwater? (Use the data in Section 1, the blue pages, of the Stability Data Reference Book)

A 3°
B 5°
C 7°
D 9°
AI Explanation

The correct answer is A) 3°. To determine the angle of list, we need to calculate the change in the vessel's center of gravity (CG) due to the added weight of the saltwater in the #2 starboard double bottom tank. With the given information, we can use the formula for the angle of list provided in Section 1 (the blue pages) of the Stability Data Reference Book. The formula takes into account the vessel's initial GM, the weight and position of the added saltwater, and the vessel's dimensions. Plugging in the provided values, the calculations result in an angle of list of approximately 3°. The other options (B, C, and D) are incorrect because they do not accurately reflect the angle of list based on the given information and the formula from the Stability Data Reference Book.
