Abstract
A wakesurfing boat for creating a wave suitable for surfing in the wake of the boat. A length to beam (L/B) ratio of 3.21 combined with a rounded hull bottom proximate the transom minimizes losses in the wake wave. Elliptical arcuate portions extending from starboard and port points on the transom to selected positions on the respective starboard and port bulwarks further minimize losses in the wake wave. The hull bottom defines an M-shaped portion and a V-shaped portion. A propulsion system includes an exhaust pipe projecting from the hull bottom below the waterline, with an exhaust opening forward of the transom. A propeller has a hub and at least three blades. A blade area, defined by a sum of the area of the blades, is larger than 70% of a disc area, defined by a sum of the hub and the blades.
