Question 147Safety & Environmental - Assistant Engineer

The correct answer is B) height of the center of gravity above the keel. KG, or the height of the center of gravity above the keel, is a critical stability parameter that determines a vessel's stability characteristics. It represents the vertical distance between the vessel's center of gravity and the keel, which is the lowest structural part of the hull. This value is essential in calculating a vessel's stability, as it directly affects the vessel's ability to resist heeling and capsizing. The other options are incorrect because they do not accurately define the KG parameter. Option A refers to the center of buoyancy, which is a different stability parameter. Option C is the metacentric height, which is a separate measure of a vessel's initial stability. Option D describes the height of the metacenter, which is also a distinct stability factor from the KG.
