ABSTRACT:
A boat with a controllable wake, including a boat hull with a propulsion system. A wake controlling device includes first and second plates with a bottom surface which is convexly curved between their forward and rear ends, and first and second mounts secured to the port and starboard sides, respectively, of the boat transom and securing the forward ends of the plates for pivoting about axes which are behind the boat transom and generally lie parallel to the plane of the aft boat bottom adjacent the first and second mounts. Plate controls extend between the transom and the plates to adjustably pivot the plates relative to the mounts. A plurality of generally triangular fins extend from the plates at substantially right angles to the plate bottom surfaces and extend at substantially right angles from the axes. Side plates are on the lateral edges of the first and second plates.
