Abstract

Abstract A standard windsurfer having a surfboard-type body provided with a daggerboard and having a mast and boom that support a sail on the surfboard is formed with an upwardly open storage compartment that is normally covered by a reversible lid. One side of the lid is smooth and when turned up forms a smooth continuation of the upper surface of the surfboard. The other side is formed with a seat which when turned up provides a stable sitting place for the user of the windsurfer who may also place his or her feet in recesses in front of this seat. The mast and boom may be held on the top of the surfboard by means of clips, with the mast passing through a groove formed in the seat. The storage compartment contains auxiliary propulsion equipment such as a paddle which may fit into the end of a mast section, or a small electric outboard motor.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 199 words
A windsurfer comprising: an elongated floatable surfer body having an upper surface and formed with an openable storage compartment which is configurated as a recess in said body; a daggerboard mountable on said body in a position projecting downwardly therefrom; a removable lid formed as a flat plate having one side provided with a raised seat and another generally flat side, said lid fitting over said compartment in a windsurfing position with said seat engaged in said compartment and said flat side up, and in a riding position with said seat up so as to support a user in a sitting position and said flat side turned toward said compartment; a mast securable to said upper surface of said body; a boom secured to said mast; and means engageable in water supporting said body for propelling said body in the water and storable in said compartment, said means for propelling including two paddles receivable in said compartment and each having a respective handle, said mast being formed at its ends with recesses each adapted to snugly receive a respective paddle handle in such a position that said mast with said paddles in said recess is a double-blade kayak-type paddle.
Claim 2
Dependent Claim 199 words
A windsurfer comprising: an elongated floatable surfer body having an upper surface and formed with an openable storage compartment which is configurated as a recess in said body; a daggerboard mountable on said body in a position projecting downwardly therefrom; a removable lid formed as a flat plate having one side provided with a raised seat and another generally flat side, said lid fitting over said compartment in a windsurfing position with said seat engaged in said compartment and said flat side up, and in a riding position with said seat up so as to support a user in a sitting position and said flat side turned toward said compartment; a mast securable to said upper surface of said body; a boom secured to said mast; and means engageable in water supporting said body for propelling said body in the water and storable in said compartment, said means for propelling including two paddles receivable in said compartment and each having a respective handle, said mast being formed at its ends with recesses each adapted to snugly receive a respective paddle handle in such a position that said mast with said paddles in said recess is a double-blade kayak-type paddle.
Claim 3
Dependent Claim 203 words
A windsurfer comprising: an elongated floatable surfer body having an upper surface and an openable storage compartment which is constituted as a recess in said body; a mast securable to said upper surface; a boom secured to said mast; means engageable in water supporting said body for propelling said body in the water, said means being storable in said compartment; a daggerboard mountable on said body in a position projecting downwardly therefrom; and a removable lid arranged to close said recess and formed as a substantially flat plate having two side surfaces, one of said side surfaces of said plate being substantially flat whereas the other side surface is provided with a raised formation forming a seat which is raised above said other side surface, said plate being fitted over said recess in a windsurfing position in which said other side surface faces toward and said raised seat extends into said recess whereas said one flat surface faces upwardly so that it presents no hindrance to windsurfing, and in a riding position in which said flat one side surface faces toward said recess whereas said other surface and said raised seat face upwardly so that a user can sit on said raised seat.
Claim 4
Dependent Claim 203 words
A windsurfer comprising: an elongated floatable surfer body having an upper surface and an openable storage compartment which is constituted as a recess in said body; a mast securable to said upper surface; a boom secured to said mast; means engageable in water supporting said body for propelling said body in the water, said means being storable in said compartment; a daggerboard mountable on said body in a position projecting downwardly therefrom; and a removable lid arranged to close said recess and formed as a substantially flat plate having two side surfaces, one of said side surfaces of said plate being substantially flat whereas the other side surface is provided with a raised formation forming a seat which is raised above said other side surface, said plate being fitted over said recess in a windsurfing position in which said other side surface faces toward and said raised seat extends into said recess whereas said one flat surface faces upwardly so that it presents no hindrance to windsurfing, and in a riding position in which said flat one side surface faces toward said recess whereas said other surface and said raised seat face upwardly so that a user can sit on said raised seat.
