Question 2581Deck Safety70% to pass
The SS AMERICAN MARINER is partially loaded with a GM of 3.1 feet and drafts of: FWD 19'-06", AFT 21'-04". Use the white pages of the Stability Data Reference Book to determine what tank(s) you should ballast to increase the GM to 3.7 feet.
AI Explanation
The correct answer is D) Tanks: DB3, DT8.
To increase the GM (Metacentric Height) from 3.1 feet to 3.7 feet, you need to add ballast to the vessel. By referring to the Stability Data Reference Book, you can determine which tanks should be ballasted to achieve the desired GM.
In this case, ballasting tanks DB3 and DT8 will increase the GM to 3.7 feet. The other answer choices are incorrect because they do not provide the appropriate combination of tanks to reach the target GM.
