Question 2192 Deck Safety

The correct answer is C) righting moment. The righting moment is the true measure of a vessel's stability at all angles of inclination. The righting moment is the force that acts to restore the vessel's upright position when it is heeled or inclined. It is calculated as the product of the vessel's weight and the distance between the center of gravity and the center of buoyancy. The righting moment increases as the vessel heels, reaching a maximum at the angle of maximum righting moment, which is a key indicator of the vessel's overall stability. The other options are incorrect because: A) Metacentric height is a measure of initial stability, but does not fully characterize stability at all angles. B) Inclining moment is the moment that causes the vessel to heel, not the moment that restores it. D) Displacement is a measure of the vessel's weight, not its stability.
