Question 2442Deck Safety70% to pass
The SS AMERICAN MARINER is ready to bunker with drafts of FWD 13'-10", AFT 16'-04". After all bunkers are on board, soundings indicate the tonnages shown in table ST-0187 below. Use the white pages of The Stability Data Reference Book to determine the free surface correction.
AI Explanation
The correct answer is C) 0.73 foot.
To determine the free surface correction, we need to use the white pages of The Stability Data Reference Book and the provided tank soundings from table ST-0187. The free surface correction is based on the free surface moments, which can be calculated from the tank dimensions and liquid levels.
The white pages provide the necessary data to calculate the free surface moment for each tank, and the total free surface correction is the sum of the individual corrections. Applying this process to the given information leads to a free surface correction of 0.73 foot, which makes answer C the correct choice.
The other answer choices are incorrect because they do not match the proper calculation using the provided data and reference material.
