Abstract

The aquatic propulsion proposed uses oscillating blades provided with independent, mutually parallel vertical shafts affixed, at the upper end thereof, to a single horizontal oar of planar profile. The blades or fins being of different length on the basis of the distance between the fastening point of the actual oscillation shaft thereof and the shaft on which the oar rocks. Propulsion is achieved when the user applies a force in traction or thrust on any of the two grips provided at either end of the handlebars, or in opposite directions on both at one and the same time. The movement is transmitted to the rotary shaft and then to the profile section on which the fins are arranged, which causes the fins to move transversely and alternately in both directions, causing displacement of the water and the propulsion of the swimmer or floating object or vehicle, in the intended direction.
