Question 145Safety & Environmental - Assistant Engineer

The correct answer is B) original vertical centerline. With no environmental forces acting on the vessel, the center of gravity of an inclined vessel will remain vertically aligned with the original vertical centerline of the vessel. This is because without any external forces, the vessel will simply tilt or heel about its original vertical axis, with the center of gravity moving directly over the centerline. The other options are incorrect because the center of flotation, metacenter, and longitudinal centerline do not necessarily correspond to the location of the center of gravity in an inclined, unforced vessel.
