           The position of the centre of buoyancy changes as:

           The centre of buoyancy is the point that the forces created by the buoyancy of the hull can be considered to act through.  | 
      
          The centre of gravity. | 
        ||
| 
           The position of the centre of gravity is governed by: 
 The lower the centre of gravity the better for stability.  | 
        
 
  | 
        The centre of gravity is the point through which the weight of the vessel can be considered to act.
