Question 1994Deck Safety70% to pass
A vessel behaves as if all of its weight is acting downward through the center of gravity, and all its support is acting upward through the _______________.
AI Explanation
The correct answer is D) center of buoyancy.
When a vessel is floating, its weight acts downward through the center of gravity, and the buoyant force acts upward through the center of buoyancy. The center of buoyancy is the point where the buoyant force, which supports the vessel, is considered to be acting. This is a fundamental principle of naval architecture and vessel stability.
The other options are incorrect because: A) the tipping center is not the point of support for the vessel; B) the amidships section is not the point of support; and C) the keel, while an important structural component, is not the point where the buoyant force acts.
