The SS AMERICAN MARINER is ready to sail with the load shown in table ST-0081 below. Use the white pages of The Stability Data Reference Book to determine the available GM.

Correct Answer: Option A — Available GM 2.8 ft

Analysis of loading condition ST-0081 via standard vessel stability reference tables involves summing vertical moments and applying free surface corrections. The resulting adjusted center of gravity matched against hydrostatic particulars establishes an available GM of 2.8 feet.
