ABSTRACT:
A planing seal for a vehicle having a hull with downward extending sidewalls. The seal comprises a plurality of juxtaposed supporting stays positioned parallel to and between the extended hull sidewalls. These supporting stays are connected to the hull at their forward end and remain free at their rearward end. A plurality of forming cables are attached to the hull at one of their ends and at least one of the plurality of cables attach to at least one of the supporting stays intermediate its ends. The cables have a length selected to provide a curvilinear form to the supporting member which allows independent freedom of movement of the stays toward the hull cable attach point. A flexible, non-permeable membrane extends the width of the hull between the sidewall extensions. The membrane has a spaced-apart sealed attachment to the hull fore and aft. The combination of the extended sidewalls and membrane hull attachments provide a pressurizable plenum chamber with seals supported by the stays.
