Abstract: Aspects of the invention provide a wave pool including at least one double V-shaped reef. The double V-shaped reef can include an inclined slope traversing the reef from the tip of the V-shape to the open end of the V-shape. In a round wave pool, a wave generating system can be provided within the center of the pool. The wave generating system can discharge water in a vertically upward motion to form a ring-shaped wave. The ring-shaped waves can propagate from proximate the center of the wave pool outward toward the edge thereof.

Abstract: Embodiments of the invention provide a set wave system and method for use with a pool containing water up to a water level. The set wave system can include a chamber positioned lower than the water level. The chamber can include an outlet for ejecting water from the chamber into the pool. The set wave system can include an air injector positioned in the chamber upstream of the outlet. The air injector can introduce air into the chamber causing water to move out of the outlet and into the pool to form a wave.
