237. A floating vessel will behave as if all of its weight is acting downward through which point?

A vessel's weight acts downward through its center of gravity. This point represents the location where the entire weight is considered to act for calculations. The center of buoyancy represents the buoyant force, the metacenter is used for stability analysis, and the center of flotation is related to trim; none of these represent the line of action of the vessel's weight.
