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.

Correct Answer: Option D — Tanks: DB3, DT8

Consulting the white pages of the Stability Data Reference Book for the given drafts identifies that ballasting tank DB3 and deep tank DT8 supplies the precise weight and vertical moment required to raise the GM from 3.1 to 3.7 feet.
