Question 2011 Deck Safety

The correct answer is C) center of buoyancy. With no environmental forces acting on the vessel, such as wind or waves, the center of gravity of an inclined vessel will be vertically aligned with the center of buoyancy. This is due to the principle of static equilibrium, where the weight of the vessel is balanced by the buoyant force acting through the center of buoyancy. The other options are incorrect because they do not represent the point around which the vessel's weight and buoyant force are balanced in the absence of external forces. The center of flotation and the longitudinal centerline are not directly related to the alignment of the center of gravity, while the original vertical centerline may not coincide with the center of buoyancy when the vessel is inclined.
