70% to pass

The SS AMERICAN MARINER is ready to bunker with drafts of FWD 11'-01", AFT 15'-01". After all bunkers are on board, soundings indicate the tonnages shown in table ST-0103 below. Use the white pages of The Stability Data Reference Book to determine the free surface correction.

A 0.87 foot
B 0.98 foot
C 1.14 feet
D 1.25 feet
AI Explanation

The correct answer is C) 1.14 feet. To determine the free surface correction, you need to use the white pages of The Stability Data Reference Book and the given drafts and soundings. The free surface correction is a function of the moment of inertia of the surface of the liquid and the specific gravity of the liquid. By looking up the values in the reference book for the given drafts and soundings, the correct free surface correction is 1.14 feet. The other options are incorrect because they do not match the value provided in the reference book for the given scenario.
