  • Patent number: 5213443
    Abstract: A windsurfing ramp which is flexible so as to provide a spring action and optimize the translation of windsurfing craft velocity into launch trajectory. The windsurfing ramp is compact by design, easily transported and easily assembled and installed. The windsurfing ramp is safe and eliminates the possibility of a windsurf craft rudder catching on a portion of the ramp thus injuring a sailor or damaging the windsurf craft. The ramp is made up of a plurality of substantially parallel, spaced apart tubular members which are flexible under the weight of a windsurf craft and sailor. The support members are arranged in a planar configuration such that one side edge is submerged when disposed on a body of water while an opposite side edge is elevated in the water.
