Question 2005 Deck Safety

The correct answer is A) buoyancy. The geometric center of the underwater volume of a floating vessel is the center of buoyancy. This is because the buoyant force, which is the upward force exerted by the water on the vessel, acts through the center of buoyancy. The center of buoyancy is the geometric center of the underwater volume of the vessel, and it is the point at which the buoyant force is considered to act. The other options are incorrect because they do not accurately describe the relationship between the geometric center of the underwater volume and the vessel's characteristics. The center of hydrodynamic forces, the center of flotation, and the center of gravity are all different points within the vessel, and they do not necessarily coincide with the center of buoyancy.
