A sailboarding equipment vehicle is provided in the form of a rackcart comprising an upstanding frame elongated at the base in a forward to rearward direction with spaced wheels at the forward end and a kick stand at the rear end of the base, the upstanding portion of the frame being offset slightly from the vertical to provide inclined support for a sailboard having a center edge portion resting on the base of the frame, the upper portion of the frame having an elongated tubular part supporting a longer rotatable member extending front to rear of the frame with a hand grip portion protruding from the rear of the frame, clamp member joined to the rotatable member at portions thereof externally of the tubular part protruding from the board side of the frame having a downwardly offset portion providing a board clamp in one position of rotation thereof, the rotatable member being releasably secured in different positions of rotatable adjustment, outer extremities of the board clamp member providing hook portions for suspending equipment from the frame, and the upwardly inclined portion of the frame opposed to the board engaging portion thereof having vertically spaced members extending longitudinally of the frame, providing boom and mast racks, whereby all equipment needed for sailboarding can be mounted on, and transported by, the vehicle.

1. A sailboarding equipment vehicle in the form of a rackcart comprising a base and an upstanding frame elongated in a front to rear direction, said base having spaced wheels at the front end and a kick stand at the rear end of the base, the upstanding portion of the frame being offset slightly from the vertical to provide inclined support for a sailboard having a center edge portion resting on the base of said frame, the upper portion of said frame having an elongated tubular part extending from the front to the rear of said frame, said tubular part supporting a longer rotatable member with a hand grip portion protruding from the rear of the frame, means joined to said rotatable member at portions thereof externally of said tubular part protruding from the board side of the frame and having a downwardly offset portion for providing a board clamp in one position of rotation thereof, means for releasably securing said rotatable member in different positions of rotatable adjustment, said board clamp having offsets providing hook portions for suspending equipment from said frame when in the board clamping position, and the upwardly inclined portion of said frame on the side opposed to the board engaging portion thereof having vertically spaced means extending longitudinally of the frame for providing boom and mast racks, whereby all equipment needed for sailboarding can be mounted on and transported by said vehicle. 2. A sailboarding equipment vehicle as defined in claim 1, wherein the base of said frame includes a low upstanding board retaining means spaced from, and essentially parallel to, the upstanding portion of said frame. 3. A sailboarding equipment vehicle as defined in claim 2, wherein said board retaining means is an irregularly contoured member fixedly secured to front and rear portions of said frame base, and the central portion of said member being offset downwardly and in the direction of said upstanding frame portion to provide hand access for gripping a board edge during sailboard loading and unloading operations. 4. A sailboarding equipment vehicle as defined in claim 1, wherein the extremities of the wheel, kick stand, mast hook and boom hook are in substantially coplanar alignment perpendicularly with respect to the wheel axle, thereby providing compact storage of the vehicle against a vertical surface. 5. A sailboarding equipment vehicle as defined in claim 4, wherein a third hook member, secured to said upper tubular frame part, and sharing in said coplanar alignment, provides means for hanging said vehicle on a vertical surface for storage purposes. 6. A sailboarding equipment vehicle as defined in claim 1, wherein said kick stand is axially spring tensioned to be normally supported in an elevated, essentially horizontal position, said kick stand being rotatably movable against the spring tension through an angle somewhat greater than 90° to a vehicle supporting position, and said kick stand being retained in such supporting position by the weight of the vehicle until being automatically released by the raising of the rear end of said vehicle. 7. A sailboarding equipment vehicle as defined in claim 6, wherein said kick stand is an open loop having spaced upper ends adapted to coaxially align with a transverse tubular portion of the base frame, interfitting means on said spaced end and on ends of said tubular portion providing stop means restricting the extent of rotatable movement of said kick stand. 8. A sailboarding equipment vehicle as defined in claim 7, wherein said spring tensioning is provided by a compound axle structure comprising short shaft members secured to said kick stand ends joined by reversely wound coil springs to a central shaft member rotatable within said tubular portion of the base frame, and said tubular portion having a semi-circumferential slot receiving a clamp screw carried by said central shaft member, and the degree of spring tensioning is varied by loosening, moving and retightening said clamp screw. 9. A sailboarding equipment vehicle as defined in claim 1, wherein the means for releasably securing said rotatable hand grip member in different positions of rotatable adjustment comprises a pin projecting from said rotatable member registering with circumferentially spaced notches in the rear end of said upper tubular frame part, and a coil spring around said rotatable member, said coil spring being housed within a spring retainer and exerting pressure against the forward end of said tubular frame part to normally support said pin in engagement with one of said slots, and rotary adjustment of said board clamp being accomplished by rearward pulling on said hand grip to compress said coil spring and disengage said pin. 10. A sailboarding equipment vehicle as defined in claim 9, wherein said spring retainer carries a set screw for clamping said retainer in different longitudinal positions on said rotatable member for adjusting the tension in said coil spring.
