Patent ID: 7722291

Claim:
A barreling wave generating apparatus, comprising: a channel having an inlet end, a base, and opposite first and second side walls; a water supply at the inlet end of the channel which supplies a flowing stream of water to the channel; at least one foil member having a predetermined maximum height adjustably mounted in the base of the channel; the foil member having a leading face extending towards the first side wall of the channel at an oblique angle to the flowing stream of the water and oriented at an adjustable pitch angle to the base of the channel, the leading face having a leading end and a trailing end in the flow direction, and a venturi face extending from the trailing end of the leading face and facing the first side wall to define a venturi pass between the first side wall and foil member wherein the width of the venturi pass is approximately equal to the foil member height; the leading face, venturi face, and venturi pass together being adapted to form a barreling wave; and an adjustment device which adjusts the pitch angle of the leading face of the foil member relative to the base of the channel to control travel of the barreling wave across the foil member.
