Abstract: A wave-forming generator for generating inclined surfaces on a contained body of water. The water is propelled against the surface-shaping generator with sufficient force to impart the desired shape to the water surface, and the generated surfaces can include waves, such as tunnel waves, appropriate for surfing and other water skimming manuevers on the surface of a body of water. Surfaces generated can require a wide range of skills to negotiate, from beginning to advanced levels. The surfaces generated are substantially stationary with respect to the water containment means, the water itself moving with respect thereto.
