The SS AMERICAN MARINER is ready to sail with the load shown in table ST-0052 below. Use the white pages of The Stability Data Reference Book to determine the available GM.

Correct Answer: Option C — Available GM 3.8 ft

Using standard stability reference data for loading condition ST-0052, total displacement and composite vertical centers of gravity are calculated. Subtracting the adjusted KG from the transverse metacentric height (KM) corresponding to the final draft results in an available GM of 3.8 feet.
