This paddle device can also be used in a reverse fashion by rotating the paddle blade 180 degrees so as to be used when navigating a watercraft with the water current in order to help stabilize the watercraft by using the force of the current against the propeller blades and the energy generated by the orifices to aid in controlling the watercraft.
