The SS AMERICAN MARINER is ready to bunker with drafts of FWD 21'-04", AFT 26'-04". After all bunkers are on board, soundings indicate the tonnages shown in table ST-0177 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 21'-04", AFT 26'-04". After all bunkers are on board, soundings indicate the tonnages shown  in table ST-0177 below. Use the white pages of The Stability Data Reference Book to determine the free surface correction.

Accepted Answer

Option A: 0.62 foot. Entering table ST-0177 with final bunker soundings gives the exact summation of free surface moments needed to determine the correct virtual rise in vertical center of gravity of 0.62 foot.
