The center of buoyancy is located at the center of gravity of the displaced liquid
For stability of a submerged body, the center of gravity of body must lie directly below the center of buoyancy
If C.G. and center of buoyancy coincide, the submerged body must lie at neutral equilibrium for all positions
All floating bodies are stable
