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. The apparatus may further comprise a tether attached to each float at the user's ankle height. Accessories may be attached to one or more floats. The invention further provides a number of propulsion mechanisms, one of which comprises a support structure, a buoyant flap articulated to the support member by an articulation having an axis of rotation that is both within 45 degrees of horizontal and substantially perpendicular to the direction of travel, said flap being movable substantially in rotation about said axis, said rotation being in a semicylindrical space behind said axis, said space being away from said direction of travel. Additional novel features of the apparatus and propulsion mechanism are discussed herein. |
