Aboard a vessel, dividing the sum of the vertical moments by the total weight yields the vessel's __________.

Correct Answer: Option A — height of the center of gravity

The vertical center of gravity (KG) is determined by the principle of moments. By summing the vertical moments (weight multiplied by height above the baseline) and dividing by the total displacement, you derive the vertical position of the center of gravity, a fundamental calculation for maintaining vessel stability under 46 CFR.
