Question 2003 Deck Safety

The correct answer is C) center of buoyancy. The center of buoyancy is the geometric center of the underwater volume of a floating object, such as a ship or boat. This is the point where the total buoyant force acts, and it is a critical factor in determining the stability and balance of the vessel. The other options are incorrect: A) The center of flotation is the point where the waterplane intersects the vessel, not the underwater volume. B) The center of gravity is the point where the weight of the vessel is concentrated, not the buoyant force. D) The tipping center is the point about which a vessel may potentially tip or capsize, not the geometric center of the underwater volume.
