The SS AMERICAN MARINER is ready to bunker with drafts of FWD 13'-10", AFT 16'-04". After all bunkers are on board, soundings indicate the tonnages shown in table ST-0187 below. Use the white pages of The Stability Data Reference Book to determine the free surface correction.

Correct Answer: Option C — 0.73 foot

Free surface correction (FSC) is calculated using the formula: FSC = (Sum of i) / Displacement, where 'i' is the transverse moment of inertia of the tank's free surface. Using the Stability Data Reference Book tables for the specific bunker soundings, the correction is determined to be 0.73 feet.
