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.

Correct Answer: Option B — Tank: DB3

Reference to vessel stability data for drafts 16'-00" forward and 18'-04" aft proves that ballasting only double bottom tank DB3 achieves the incremental vertical moment necessary to raise the GM from 3.1 to 3.6 feet.
