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

A dividing by displacement
B multiplying by displacement
C adding the free surface correction
D subtracting the free surface correction
AI Explanation

The correct answer is A) dividing by displacement. The longitudinal center of gravity (LCG) is obtained by dividing the sum of the longitudinal moments by the displacement of the vessel. This is the standard calculation used to determine the longitudinal center of gravity, as per the regulations and guidelines for the US Coast Guard Captain's License Examinations. The other options are incorrect because B) multiplying by displacement would not yield the LCG, C) adding the free surface correction is not the correct formula for obtaining the LCG, and D) subtracting the free surface correction is also not the correct way to calculate the LCG.
