  • Docking apparatus
    Patent number: 6131528
    Abstract: A docking apparatus includes a pair of spaced apart primary buoyancy bodies and cradle assemblies extending between the bodies, the primary buoyancy bodies being capable of being filled with water and thus submerged, to enable a water craft to be positioned over the cradle assemblies and lifted clear of the water when water is expelled from the bodies. The cradles include flexible sheets of a V-shaped configuration which adjust to the shape of the water craft seating thereon to enable the docking apparatus to be used with a range of hulls of different forms.
