Question 152Safety & Environmental - Assistant Engineer

The correct answer is D) KB. KB (Keel to Buoyancy) represents the height of the center of buoyancy, which is the vertical distance from the keel to the center of buoyancy of the vessel. This is an important parameter in determining the vessel's stability and is a key factor in the US Coast Guard Captain's License Examinations. The other options are incorrect: A) BM (Metacentric Height) represents the distance between the center of gravity and the metacenter, which is a different stability parameter. B) CB (Center of Buoyancy) represents the location of the center of buoyancy, not its height. C) BK (Keel to Buoyancy) is not a standard abbreviation and does not represent the height of the center of buoyancy.
