The SS AMERICAN MARINER is partially loaded with a GM of 3.1 feet and drafts of: FWD 16'-00", AFT 18'-04". Use the white pages of the Stability Data Reference Book to determine what tank(s) you should ballast to increase the GM to 3.6 feet.
AI Explanation
The correct answer is B) Tank: DB3.
To increase the GM (Metacentric Height) from 3.1 feet to 3.6 feet, you need to add ballast in a tank that will raise the center of gravity (KG) of the vessel. Based on the Stability Data Reference Book, the DB3 tank is the most appropriate choice, as it is located low in the vessel and will effectively increase the GM to the desired 3.6 feet.
The other answer choices are incorrect because they do not provide the optimal solution to raise the GM to 3.6 feet. Tanks DT6 and DT7 (option A) are not located as low in the vessel as DB3, and tanks DB1 and DT1A (option C) may not provide the necessary increase in GM. Tank DT8 (option D) is not the best choice, as it is not as effective in raising the GM as the DB3 tank.
