Abstract
An apparatus for the purpose of floatation and transportation on water comprises a pair of buoyant wing-shaped floats and foot wells in the floats designed to be under the center of buoyancy of each float. Accessories may be attached to one or more floats. Additional novel features and aspects of the invention are disclosed herein.
Claims35
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 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.
A human powered apparatus for use by a user for the purpose of floatation and transportation on water in a direction, comprising:
- a first buoyant float and a second buoyant float, each of said first buoyant float and said second buoyant float comprising a center of buoyancy, a bow, and a stern, and further comprising:
- a substantially straight and generally flat side running from said bow to said stern;
- a substantially convex side running from said bow to said stern;
- a bottom side in watertight connection with said substantially straight side and said substantially convex outward side;
- a top surface;
- and
- a foot well for housing said user's foot and ankle, said foot well disposed through said top surface of said buoyant float and extending toward said bottom side, said foot well further located to position said user's ankle substantially in vertical alignment with the center of buoyancy, and said foot well further comprising a bottom surface that is below said center of buoyancy.
