US Patent 9855995 Wake shaping device and system

Boats can be adapted to generate a wake that is well-suited for the sport of wake surfing. For example, boats can include an aft platform with a contoured underside that contacts water to generate such a wake for wake surfing. In some embodiments, the contoured underside of the platform includes dual opposing wake-shaping surfaces that shape the water flowing aft from the boat hull to create a wake shape that is well-suited for wake surfing. The aft platforms can be integrally manufactured as an extension to the hull or deck of a new boat, or manufactured separately and subsequently affixed to a previously manufactured boat.
