Question 2145 Deck Safety

The correct answer is B) metacenter. The metacenter is the point to which a vessel's center of gravity (G) may rise and still permit the vessel to have positive stability. When a vessel is heeled or inclined, the metacenter remains above the center of gravity, which allows the vessel to develop a righting moment to return to an upright position. The other options are incorrect: A) Metacentric point - This is not a standard term in naval architecture. C) Tipping center - This refers to the point where a vessel would begin to capsize, not the point of positive stability. D) Metacentric radius - This is the distance between the metacenter and the vessel's center of buoyancy, not the point of positive stability.
