Abstract
A highly maneuverable water sled device is disclosed which includes a joystick for controlling a rudder and an elevator. The base of the water sled device is provided with upwardly extending, hollow side, front and rear walls which are individually fillable with water to vary the buoyancy of the device. A preferred embodiment of this invention further includes a hydrofoil assembly downwardly extending from a forward section of the device and a flotation mattress attached to an upper surface of the device to provide for user comfort and to further allow the buoyancy of the device to be controlled.
Claims6
A water sled device comprising:
- an elongated base having a forward and a rearward end, and a pair of upwardly extending sidewalls;
- downwardly extending bracket means attached proximate the rearward end of said base;
- rudder means and elevator means pivotally supported by said bracket means;
- a control bar having ends rotatably supported by said sidewalls;
- a control stick pivotally attached to a mid-length portion of said control bar for longitudinal and lateral motion relative said base;
- control cable means defining a closed loop connecting said control stick and said rudder, whereby lateral motion of said control stick controls the position of said rudder means;
- and
- elevator actuator means including a first elevator actuator bar upwardly extending from said elevator means and a second elevator actuator bar coupled at one end to said first elevator actuator bar and coupled at its other end to said control means, whereby longitudinal motion of said control stick controls the position of said elevator means.
