In the COASTAL DRILLER, LCG is obtained from the sum of the longitudinal moments by _______________.

A subtracting the sum of the weights
B multiplying by the sum of the weights
C dividing by the sum of the weights
D adding the sum of the weights
AI Explanation

The correct answer is C) dividing by the sum of the weights. The longitudinal center of gravity (LCG) is obtained by dividing the sum of the longitudinal moments by the sum of the weights. This is because the LCG represents the location of the overall center of gravity of the vessel along the longitudinal (length) axis, and it is calculated by taking the weighted average of the individual component locations. The other options are incorrect because subtracting or adding the sum of the weights would not yield the LCG, and multiplying by the sum of the weights would not provide the proper calculation to determine the LCG.
