The present flying ski is designed to be towed behind a conventional powered watercraft by a standard ski tow rope or similar device having a handle that can be held by a human rider. In use, the rider is seated on the seat of the flying ski and towed by the watercraft. The improved flying ski comprises an elongate board and a seat that extends generally perpendicular to and upward from the board to support the seated rider's buttocks. The seat preferably includes a flexible C-shaped member for absorbing impacts during use. The rider's legs extend toward the front of the board and are secured by a pair of foot holders that attach to the board. An elongate strut extends downward from the board and couples the seat to a planing blade. The elongate strut is preferably formed with a V-shape wherein the length from the front edge to the back edge of the strut is greater along an upper portion for enhanced structural integrity. The planing blade advantageously has a front blade and a rear blade interconnected by a fuselage. The rear blade may be located above the front blade for avoiding turbulence from the front blade. The present flying ski accommodates a variety of rider skill levels by incorporating a mechanism and system that allows the rider to selectively adjust performance characteristics of the ski. In particular, the rider can control stability, lift and maneuverability characteristics to accommodate the rider's particular skill level and the particular challenge that the rider seeks. The position of the rear blade may be moved forward or backward to change the hydrodynamic characteristics of the flying ski. In addition, the present flying ski includes a detachable back support that allows handicapped riders to enjoy the thrills of using the ski. The present flying ski also provides for quick and easy attachment and detachment of component parts of the ski. This feature allows the ski to be more easily transported when not in use and reduces the risk of accidentally dropping or otherwise damaging the ski.

What is claimed is: 1. A recreational device that supports a seated human rider while the rider and the device are towed behind a powered watercraft, comprising: an elongated board having a front end and a back end; a seat portion extending upward from a top side of the board; a strut extending downward from a bottom side of the board; a fuselage extending from a bottom end of the strut; a front blade assembly provided along a front end portion of the fuselage; and a rear blade assembly provided along a rear end portion of the fuselage; wherein the rear blade assembly is vertically displaced from the front blade assembly, such that the rear blade assembly occupies a higher elevation than the front blade assembly; and the fuselage includes a lower surface, the fuselage lower surface tapering upward toward a rear end of the fuselage; and the rear blade assembly includes upswept wings and a central valley disposed between the wings. 2. The recreational device of claim 1, wherein the rear blade assembly is coupled to a top side of the fuselage, and the front blade assembly is coupled to a bottom side of the fuselage. 3. The recreational device of claim 1, wherein the front blade assembly includes upswept wings and a central valley disposed between the wings. 4. The recreational device of claim 1, wherein each upswept wing of the rear blade assembly includes a lateral portion defining a substantially vertical surface. 5. A recreational device that supports a seated human rider while the rider and the device are towed behind a powered watercraft, comprising: an elongated board having a front end and a back end; a seat portion extending upward from a top side of the board; a strut extending downward from a bottom side of the board; a fuselage extending from a bottom end of the strut; a front blade assembly provided along a front end portion of the fuselage; and a rear blade assembly provided along a rear end portion of the fuselage; wherein the front blade assembly includes a protruding tongue portion that extends rearward from a main body portion of the front blade assembly. 6. The recreational device of claim 5, wherein the rear blade assembly is vertically displaced from the front blade assembly. 7. The recreational device of claim 6, wherein the rear blade assembly occupies a higher elevation than the front blade assembly. 8. The recreational device of claim 5, wherein the front blade assembly is coupled to a bottom side of the fuselage. 9. The recreational device of claim 8, wherein at least a portion of the tongue portion extends beneath the strut. 10. The recreational device of claim 5, wherein at least a portion of the tongue portion has a width greater than a width of the fuselage as measured along a junction of the tongue portion and the fuselage.
