This unique combination gives a Bladerunner phenomenal aerodynamic lift, which improves performance and significantly softens the ride over conventional monohulls by compressing the air inside the tunnels adding a cushioning effect. A further advantage is that the centre of lift is located much further aft than a comparative high performance catamaran, providing a safer and more level ride in rough seas. The sharp keels of a Bladerunner’s sponsons cut effortlessly through the waves, which is a stark contrast to the wide flat chines of a conventional monohull that impact hard on the surface of the water. They also form the outer walls of the tunnels, which is essential for air compression and the resulting aerodynamic lift.
