The SS AMERICAN MARINER is ready to sail with the load shown in table ST-0056 below. Use the white pages of The Stability Data Reference Book to determine the available GM.

Correct Answer: Option D — Available GM 4.1 ft

Evaluating stability reference table ST-0056 requires cross-referencing cargo weight, vertical center of gravity (KG), and free surface corrections. Entering the vessel's hydrostatic curves with total displacement and corrected KG for this specific loading condition confirms an available GM of 4.1 feet.
