ABSTRACT:
The rear end of a slab-type hull of the sort utilized for windsurfing, and also as disclosed herein adapted to be used in the place of a slalom ski, is horizontally bifurcated to define a rigid upper deck portion and a flexible deflection panel extending beneath, and spaced from, the upper rear deck portion. The deflection panel can flex upwardly independently of the upper, rigid rear deck. Although the flexure of the deflection panel beneath the upper rear deck is functional without any further controls or modifications other than the independent flexure of the deflection panel itself relative to the overlying upper rear deck, its characteristics are enhanced by incorporating certain control features in the nature of a detent element which fixes the curvature of the deflection panel, and/or one or more stops, preferably spring-loaded, which determine the uppermost deflection of a certain portion or portions of the deflection panel. When the hull is used with a windsurfer or in place of a slalom ski, it substantially enhances certain of the capabilities of the hull as are described in more detail herein.
