Question 2457 Deck Safety

70% to pass

The SS AMERICAN MARINER is ready to bunker with drafts of FWD 14'-06", AFT 17'-00". After all bunkers are on board, soundings indicate the tonnages shown in table ST-0085 below. Use the white pages of The Stability Data Reference Book to determine the free surface correction.

A 0.52 foot
B 0.70 foot
C 0.84 foot
D 1.10 feet
AI Explanation

The correct answer is C) 0.84 foot. To determine the free surface correction, we need to use the white pages of The Stability Data Reference Book and the given drafts and soundings. The free surface correction is a function of the free surface moment, which is calculated based on the tank dimensions and liquid levels. Given the drafts and soundings, we can find the free surface moment for the tanks in the table ST-0085 and then use the white pages to determine the corresponding free surface correction of 0.84 foot. The other options are incorrect because they do not match the correct free surface correction value obtained from the reference book using the provided information.
