The SS AMERICAN MARINER is ready to bunker with drafts of FWD 12'-07", AFT 16'-01". After all bunkers are on board, soundings indicate the tonnages shown in table ST-0167 below. Use the white pages of The Stability Data Reference Book to determine the free surface correction.

Question

The SS AMERICAN MARINER is ready to bunker with drafts of FWD 12'-07", AFT 16'-01". After all bunkers are on board, soundings indicate the tonnages shown  in table ST-0167 below. Use the white pages of The Stability Data Reference Book to determine the free surface correction.

Accepted Answer

Option B: 1.07 foot. Free surface correction (FSC) is calculated using the formula FSC = (Sum of Moments of Inertia × Specific Gravity of Liquid) / Vessel's Displacement. Utilizing the standard Stability Data Reference Book for the SS AMERICAN MARINER yields the correct free surface reduction of 1.07 feet.
