The SS AMERICAN MARINER is ready to sail with the load shown in table ST-0078 below. Use the white pages of The Stability Data Reference Book to determine the available GM.

A Available GM 3.6 ft
B Available GM 3.3 ft
C Available GM 3.1 ft
D Available GM 3.8 ft
AI Explanation

The correct answer is C) Available GM 3.1 ft. To determine the available GM (Metacentric Height), you need to use the white pages of The Stability Data Reference Book and the load information provided in table ST-0078. The white pages contain the stability data for the vessel, and by inputting the load conditions, you can calculate the available GM. Based on the information given, the available GM is 3.1 ft, as indicated in the correct answer. The other options are incorrect as they do not match the GM value calculated using the provided stability data.
