The robot blade includes a second end distal the first end, in which the second end has a plan view profile that forms a continuously curved surface.

Abstract: A water craft constituted by a fiberglass body with a streamlined bow in back of which is a recess forming a seating compartment. The rear end of the body is formed to provide a keel. Front-to-back guides in the seating compartment support a shiftable seat having dismountable arms that extend laterally to opposite sides of the body to support floats at their ends. In front of the seat, pedals are supplied which are kinematically joined to a central shaft within the body that is connected to a drive shaft that emerges from the body for driving a propeller.
