Question 2008 Deck Safety

The correct answer is B) center of buoyancy. The center of buoyancy is the center of the underwater volume of a floating vessel. This is a critical point in determining the vessel's stability, as the buoyant force acts through the center of buoyancy. The location of the center of buoyancy is essential for calculating the righting moments that keep the vessel upright and stable. The other options are incorrect because: A) the uncorrected height of the center of gravity does not account for the underwater volume, C) the center of flotation refers to the waterline, not the underwater volume, and D) the center of gravity corrected for free surface effects is a different parameter related to the vessel's stability.
