Question 2144 Deck Safety

The correct answer is C) at the same height as the center of gravity. In a neutral equilibrium position, the metacenter (the point where the upright buoyancy force acts) is located at the same height as the center of gravity of the vessel. This means that when the vessel is inclined, the restoring moment is zero, and the vessel will remain in its inclined position without a tendency to return to the upright position or capsize. The other options are incorrect because: A) the metacenter is not necessarily at midships, B) the metacenter is above the keel, and D) the metacenter is not necessarily at the center of the waterplane area.
