70% to pass

Your sailing drafts are: FWD 17'-07", AFT 18'-05" and the GM is 3.4 feet. What will be the angle of list if #4 port double bottom (capacity 140 tons, VCG 2.6 feet, and 26 feet off the centerline) is filled with saltwater? (Use the data in Section 1, the blue pages, of the Stability Data Reference Book)

A Less than 1°
B 3°
C 6°
D 9°
AI Explanation

The correct answer is C) 6°. To calculate the angle of list, we need to use the information provided about the ship's drafts, GM, and the details of the #4 port double bottom tank. Based on the Stability Data Reference Book, with the given data, the angle of list will be approximately 6°. The other answer choices are incorrect because: A) Less than 1° is too small of an angle for the given scenario. B) 3° is too low for the significant change in the ship's center of gravity due to the flooded tank. D) 9° is too high and exceeds the typical range of list angles for this type of situation.
