ABSTRACT:
There is provided a toy of a substantially elongated configuration having, in part, a generally rectangular member inclined at an acute angle with a surface over which the toy would be thrown. Continuously adjacent along the longitudinal edges and depending downwardly therefrom are two side skirts, preferably having an acute triangular shape. The acute angle of said triangle would be determined by, although not necessarily identical to, the acute angle made by the top member with the surface when the toy is at rest on that surface. The toy further having a pin to orient the toy as it travels, preferably a dorsal fin disposed near the trailing end of the toy, a handle disposed approximately two-thirds of the distance from the leading end to the trailing end of the toy, and a weight disposed near the leading end of the toy to minimize sailing of the leading end of the toy out of close proximity with the surface over which the toy is thrown. The toy is supported by ground effect when moving forward at sufficient velocity, being supported on a very low friction layer of air which is trapped in a cavity between the side skirts, and leaks from beneath the lower edges of the side skirts and trailing end of the toy.
