Question 2004 Deck Safety

The correct answer is B) the geometric center of the displaced volume. The center of buoyancy is the geometric center of the volume of water displaced by the vessel. This is the point at which the buoyant force acts, as it is the point where the total buoyant force can be considered to be concentrated. The location of the center of buoyancy is directly related to the shape and distribution of the vessel's underwater volume. The other options are incorrect because they do not accurately represent the location of the center of buoyancy. The center of gravity corrected for free surface effects (D) is a different property, and the intersection of the vertical centerline and line of action of the buoyant force (A) as well as the geometric center of the waterplane area (C) are not the same as the geometric center of the displaced volume.
