In damage stability, what does reserve buoyancy refer to?

In damage stability, what does reserve buoyancy refer to?

• A. The volume of buoyant space above waterline that remains to provide buoyancy after flooding.
• B. The portion of the vessel's buoyancy that remains to provide support after flooding has occurred.
• C. A measure of weight growth during loading.
• D. The fuel capacity remaining after damage.

Answer: (B)

Reserve buoyancy is the portion of the vessel's buoyancy that remains to provide support after flooding has occurred. It is the volume of watertight, dry hull that still displaces water and provides buoyant force when damage has allowed water to enter other compartments. This remaining dry hull space is what keeps the ship afloat and contributes to stability as flooding progresses. The bigger the reserve buoyancy, the more buoyant support stays available after damage. The other options either describe something related but not equivalent (such as space above the waterline after flooding) or refer to unrelated concepts like weight growth during loading or remaining fuel capacity.
