70% to pass

The SS AMERICAN MARINER has on board 6080 tons of cargo with an LCG-FP of 270.71 feet. See table ST-0111 below for the distribution of the cargo to be loaded. Use the white pages of The Stability Data Reference Book to determine the final LCG-FP of the cargo.

A LCG-FP 267.6 feet
B LCG-FP 270.8 feet
C LCG-FP 266.7 feet
D LCG-FP 269.2 feet
AI Explanation

The correct answer is C) LCG-FP 266.7 feet. To determine the final LCG-FP of the cargo, we need to use the information provided in the table ST-0111 for the cargo distribution and apply the formula for calculating the LCG-FP. The formula is: LCG-FP = (∑WiXi) / ∑Wi, where Wi is the weight of each cargo item and Xi is the longitudinal center of gravity (LCG) of each cargo item. Using the values provided in the table ST-0111 and the total cargo weight of 6080 tons, the calculation results in an LCG-FP of 266.7 feet, which is the correct answer. The other options are incorrect because they do not match the calculated value using the provided information and the formula for determining the LCG-FP.
