Many of Tony Castronovo's designs and innovations in gasoline model boating are the foundation upon which the industry has been built. He was first to introduce surface drive on a Vee hull (propeller hub above the water line) to model boating which he named "SPD" (surface planing drive) as well as numerous products and developments relative to gasoline-powered model boating. He and his company continue to produce gasoline-powered model boats and components.
