Coften the more successful patents are in reality elaboration of things already existing in nature. Many of the most well known inventions are in fact simple equation, which in many cases results absolutely wining like in the case of the boat with a fishtail invent by Mr Di Silvestri Giuseppe, a man of only 95 years who continues to create projects of every type and nature in the most disparate technical areas. This device comes from a very careful study and it will finally allow eliminating cumbersome and expensive oars commonly in use transforming the rudder in to the most important accessory of the boats. Its functioning is simple and brilliant, since that it will suffice only to fluctuate its connected role to give a determined movement to the boat. The secret is that we have replaced the rigid part (immersed) of the abovementioned rudder, with a flexible surface in rubber that in practice behaves like a common fishtail. This simple alteration, will allow to row better since that the frictions, as the obstacles, will be considerably reduced and with the help of the special telescopic lever, more people will be able to do it simultaneously! Thanks to the innovative hook system the brilliant accessory can be advantageously placed to all the boats already existing without compromising the hydrodynamics. In virtue of this intelligent alteration, the price of the small boats will come down significantly, growing at the same time the trade of it.
