The SS AMERICAN MARINER is ready to bunker with drafts of FWD 15'-05", AFT 21'-03". After all bunkers are on board, soundings indicate the tonnages shown in table ST-0174 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 15'-05", AFT 21'-03". After all bunkers are on board, soundings indicate the tonnages shown  in table ST-0174 below. Use the white pages of The Stability Data Reference Book to determine the free surface correction.

Accepted Answer

Option B: 1.15 feet. Consulting table ST-0174 in the stability reference data manual for the given soundings yields total free surface moments that compute to an effective vertical center of gravity correction of 1.15 feet.
