In the absence of external forces, adding weight to one side of a floating vessel, will cause the vessel to __________.

Correct Answer: Option B — list until the center of buoyancy is aligned vertically with the center of gravity

When weight is added off-center, the vessel heels until the center of buoyancy shifts to a position directly beneath the new center of gravity. This alignment is required for static equilibrium. If the center of gravity is too high, the vessel may develop an angle of loll.
