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.
