Abstract
A supportive framework is disclosed for a boat having a hull which consists of a flexible plastic skin wherein the bottom frame element of the frame network is tubular and includes a rounded bottom wall which flexes inwardly to absorb stresses upon impact and more widely and uniformly distribute the stresses over the impact area.
Claims6
In a boat of the type having a hull constructed from a generally flexible plastic skin material and a supportive framework for supporting and maintaining the configuration of said hull, wherein said framework comprises:
- longitudinally extending frame means carried centrally within said hull;
- said longitudinally extending frame means including an elongated bulbous bottom frame element which includes an outwardly bulging bottom wall presenting a convexly curved exterior surface to the skin material of a bottom portion of said hull;
- and
- said bottom frame element being constructed of a sufficiently flexible material enabling said convexly curved bottom wall to flex inwardly compressing said bottom frame element upon impact of said bottom portion of said hull skin with the water or obstacles therein to distribute and relieve stress concentration on said hull effectively preventing over-flexing of said skin material and hull disfiguration (stress produced thereby).
A supportive framework for supporting and maintaining the hull configuration of a boat having a hull constructed from a plastic, generally flexible skin material, said framework comprising:
- longitudinally extending frame means extending generally centrally within the hull of said boat and extending vertically between top and bottom portions of said hull to maintain the cross-sectional configuration thereof;
- said frame means including an elongated bottom frame element having a bulbous cross-sectional configuration defined by an outwardly bulging bottom wall and spaced upper walls extending upwardly from said bottom wall to define an enclosure having a hollow core;
- said outwardly bulging bottom wall presenting a convexly curved exterior wall surface to the flexible skin material of said bottom hull portion;
- and
- said bulbous bottom frame element being sufficiently flexible enabling said outwardly bulging bottom wall to flex inwardly and compress upon impact with water or obstacles therein to distribute the stresses upon the hull and framework produced upon impact effectively preventing over-flexing of said skin material and hull disfiguration.
