Claims
- 1. A shock mitigating system for a planing boat having a hull extending from a forward end to an aft end, the hull further having a centerline running from the forward end to the aft end, said shock mitigating system comprising:a one-piece adjunct hull surface pivotally coupled at one end thereof to the forward end of the hull of said planing boat, said adjunct hull surface extending along the hull of said planing boat on either side of the centerline to aft of amidships of said planing boat, said adjunct hull surface being constructed of a rigid material that has upper and lower surfaces conforming to the shape of the hull of said planing boat on either side of the centerline; and a position controller coupled to said adjunct hull surface for selectively positioning said adjunct hull surface between a first position and a second position wherein, in said first position, said adjunct hull surface rests against the hull and wherein, in said second position, said adjunct hull surface pivots at said one end and is spaced apart from the hull, said position controller further absorbing shock loads experienced by said adjunct hull surface when said adjunct hull surface is spaced apart from the hull of said planing boat.
- 2. A shock mitigating system as in claim 1 wherein a length of said adjunct hull surface is approximately two-thirds the length of said planing boat.
- 3. A shock mitigating system as in claim 1 wherein said position controller comprises:a cylinder having a piston, said piston being coupled to said aft portion of said adjunct hull surface; and a pressure system coupled to said cylinder for selectively supplying a compressible fluid under pressure to said cylinder for controlling the position of said piston in said cylinder.
- 4. A shock mitigating system as in claim 1 wherein said compressible fluid is air.
- 5. A shock mitigating system for a planing boat having a hull extending from a forward end to an aft end, the hull further having a centerline running from the forward end to the aft end, said shock mitigating system comprising:a one-piece adjunct hull surface pivotally coupled at one end thereof to the forward end of the hull of said planing boat, said adjunct hull surface extending along the hull of said planing boat on either side of the centerline to aft of amidships of said planing boat, said adjunct hull surface being constructed of a rigid material that has upper and lower surfaces conforming to the shape of the hull of said planing boat on either side of the centerline; a spring coupled between said adjunct hull surface and said planing boat; and a biasing system coupled to said spring for biasing said spring such that said adjunct hull surface can be selectively positioned anywhere between a first position and a second position wherein, in said first position, said adjunct hull surface rests against the hull and wherein, in said second position, said adjunct hull surface pivots at said one end and is spaced apart from the hull, wherein said spring absorbs shock loads experienced by said adjunct hull surface when said adjunct hull surface is spaced apart from the hull of said planing boat.
- 6. A shock mitigating system as in claim 5 wherein a length of said adjunct hull surface is approximately two-thirds the length of said planing boat.
- 7. A shock mitigating system as in claim 5 wherein said spring is an air spring.
- 8. A shock mitigating system as in claim 5 wherein said spring is a hydraulic spring.
