Abstract: A boat hull includes a dispersion tunnel extending fore and aft forming a channel within a hull bottom surface for receiving a flow of water. A gate is inserted into and out of the channel for affecting pressure on the hull bottom with movement between open and closed positions, wherein the gate is out of the channel and fully extended into the channel. By altering the depth of the gate into the channel, hull performance and wake shape are modified as desired.

Abstract: A water sports performance boat includes a hull having a sharpened angle keel for cutting into the water. Reverse chines are carried on port and starboard sides and extending from a forward portion of the hull to an aft portion for inducing a lifting of the bow at generally low boat speeds and for providing a stabilizing effect. Port and starboard spray pockets are located at the aft portion of the hull for reducing a side spray of water near the transom. Performance strakes are formed within the hull with each extending from an aft position rearwardly to the transom. An elliptical shaped dispersion tunnel formed along the keel within an aft most portion of the hull extends through the transom and provides a desirable wake shape.
