Patent ID: 7121910

Claim:
A water walking apparatus for use by a user for moving in a direction, comprising: a first buoyant float for the user's left foot and a second buoyant float for the user's right foot, each buoyant float further comprising: a flap having a leading edge and a trailing edge, said flap being articulated to the buoyant float by an articulation, said articulation having an axis of rotation located within the first 25% of the distance between said leading edge and said trailing edge of said flap; said articulation allowing said flap to rotate between a high resistance orientation, in which the flap is approximately perpendicular to the direction and said trailing edge is above said leading edge, and a low resistance orientation, in which the flap is approximately parallel to the direction and in which the trailing edge is lower than in the high resistance orientation, wherein the flap has a positive buoyant moment, wherein said buoyant moment of said flap exerts a torque on said flap so as to rotate said flap toward the high resistance orientation, and wherein the flap's mass density is generally a gradient, said gradient decreasing in magnitude from said leading edge to said trailing edge.
