New keel for boats, characterized by the fact that the keel is formed by a central part in "V" that at the upper ends of its arms has an arched extension that descends back down and ends in smaller "V" paths and extreme, concave arms, so that on the joining surface of the arc that connects one and another small "V" with the central "V", larger, the water displaced from above is lodged by the central "V" as the vessel advances and this hydraulic cushion water acts when the boat descends on the liquid after it is lifted by the cut waves.
