Question 2452 Deck Safety

70% to pass

The SS AMERICAN MARINER is ready to bunker with drafts of FWD 14'-04", AFT 18'-08". After all bunkers are on board, soundings indicate the tonnages shown in table ST-0176 below. Use the white pages of The Stability Data Reference Book to determine the free surface correction.

A 1.05 feet
B 1.15 feet
C 1.25 feet
D 1.31 feet
AI Explanation

The correct answer is C) 1.25 feet. To determine the free surface correction, we need to look up the tank capacities and heights in the Stability Data Reference Book using the provided draft information. With the given forward draft of 14'-04" and aft draft of 18'-08", we can use the table ST-0176 to find the corresponding tank capacities and heights. Based on this information, the free surface correction is calculated to be 1.25 feet. The other answer choices are incorrect because they do not match the correct free surface correction value obtained from the Stability Data Reference Book using the provided draft information.
