Question 2583Deck Safety70% to pass
The SS AMERICAN MARINER is partially loaded with a GM of 2.6 feet and drafts of: FWD 13'-07", AFT 15'-01". Use the white pages of the Stability Data Reference Book to determine what tanks you should ballast to increase the GM to 3.4 feet.
AI Explanation
The correct answer is A) Tanks: DB6, DB7, DT7.
To increase the GM (Metacentric Height) from 2.6 feet to 3.4 feet, the vessel needs to shift weight from the aft to the forward part of the ship. This can be achieved by ballasting the tanks DB6, DB7, and DT7, which are located in the forward part of the vessel. By adding weight in the forward tanks, the vessel's trim will be adjusted, increasing the GM as required.
The other answer choices are incorrect because they do not effectively shift the weight distribution to increase the GM to the target value of 3.4 feet. Options B, C, and D do not involve the appropriate combination of tanks to achieve the desired GM.
