Abstract:
1. A wave pool comprising: a pool for containing water, the pool defining a channel having a first side wall, a second side wall, and a bottom with a contour that slopes upward from a deep area proximate the first side wall toward a sill defined by the second side wall; and at least one foil at least partially submerged in the water and configured to move along the first side wall, each of the at least one foil having a curvilinear cross-sectional geometry that includes a leading surface that is concave about a vertical axis to provide drag to generate a primary wave laterally in water that contacts the leading surface of the foil, and a trailing surface that narrows from a maximum width of the foil adjacent the leading surface to a point at an end of the foil, the trailing surface to decrease the drag of the foil and to minimize oscillatory waves that trail the primary wave from the water moving past the leading surface of the foil.
