The SS AMERICAN MARINER is ready to bunker with drafts of FWD 19'-00", AFT 24'-00". After all bunkers are on board, soundings indicate the tonnages shown in table ST-0171 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 19'-00", AFT 24'-00". After all bunkers are on board, soundings indicate the tonnages shown  in table ST-0171 below. Use the white pages of The Stability Data Reference Book to determine the free surface correction.

Accepted Answer

Option C: 0.85 foot. Entering the SS AMERICAN MARINER stability tables with table ST-0171 soundings, the cumulative free surface moments applied to total displaced weight produce the correct virtual rise in center of gravity of 0.85 foot.
