Question 2058 Deck Safety

The correct answer is A) 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. The center of gravity is the point at which the entire weight of the vessel is considered to be concentrated. Knowing the KG value allows naval architects and marine engineers to calculate the vessel's stability, including its ability to resist overturning. The other options are incorrect because: B) is the height of the metacenter, C) is the difference between the height of the metacenter and the height of the center of gravity (known as the metacentric height), and D) is the height of the center of buoyancy, which is a different stability parameter.
