A wave park includes a body of water, and a track positioned in or proximate the body of water. The wave park further includes at least one foil coupled to move along the track and be at least partially submerged in the body of water. The at least one foil has 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 of the body of 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.

A hydrofoil simulator structure comprising a tank, in which a water current is generated, and a frame, which supports an elastic trampoline positioned above the water surface of the tank; the structure also comprising a series of elastic ropes associated with a trapeze harness worn by a user who stands on a board of a hydrofoil having wings immersed in water.

A wave system is disclosed herein. The wave system may include an obstacle over which water is pushed to create a wave contoured surface for riding or maneuvering by a user.

A wave pool and wave generating mechanism are disclosed. The wave pool includes a bathymetry that includes a dynamically shapeable reef along a length or circumference of a channel that defines the wave pool. The wave generating mechanism includes a foil that has a shape for bi-directionality based on an adjustment of a yaw angle of the foil. The foil can be further controlled to increase or decrease certain surface areas or other angles of interacting with water in the wave pool.

A snowboard, snowboard assembly, and snowboard accessory for converting a snowboard into training snowboard. There is a board and a pivot member/strip. The pivot member/strip is elongated member protruding from the underside of the board along the main axis of the board. The pivot member/strip has a base width that is greater than a width of the flat bottom of the strip and greater than a height of the strip. The flat bottom of the strip is flanked by beveled edges along each side and at the front and back. The strip is either integral to the board or is couple thereto by a coupling structure (e.g. adhesive, binding, snaps, clips). The strip has a trapezoidal cross-section. Flanking beveled edges may have an acute angle with respect to the base and/or an obtuse angle with respect to the flat bottom surface.

The present invention is an artificial surfing reef for modifying a body of water's bathymetry to create surfing waves. The artificial surfing reef is a shaped structure made up of many sized and shaped Expanded Polystyrene Geo Foam blocks. As swell moves toward the shore, its bottom is resisted by the leading edge of the Expanded Polystyrene Geo Foam artificial surfing reef. As the swell transverses over the Expanded Polystyrene Geo Foam Artificial reef, the wave topples over and forms a plunging surfing wave. An earth anchor, connected to a cable, linked to a round shaped anchor disc, is attached to each Expanded Polystyrene Geo Foam block for maintaining the foam artificial reef at a desired location submersed underwater. A plurality of Expanded Polystyrene Geo Foam blocks may be attached to one another and configured so as to define a surf reef, which enhances the suitability of waves for surfing.

Wave generator system (1), comprising a continuous and elongated barrier (4) that has a front side (4a) facing a first mass of water (2) fitted with a first reef (12) and a rear side (4b) facing a second mass of water (3) fitted with a second reef (15). The barrier (4) can move along the length (L) with a serpentine movement, and the front (4a) and rear sides (4b) push water from the masses of water (2, 3) towards the respective reefs (12, 15) for the formation of waves in the first mass of water (2) and in the second mass of water (3).

A wave park includes a body of water, and a track positioned in the body of water. The wave park further includes at least one foil coupled to move along the track, and being at least partially submerged in the body of water. The foil has 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 of the body of 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.

A wave pool for generating surfable waves is disclosed. The wave pool includes a pool for containing water. The pool defines 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. The wave pool further includes at least one foil at least partially submerged in the water near the side wall, and being adapted for movement by a moving mechanism in a direction along the side wall for generating a wave in the channel that forms a breaking wave on the sill. The wave pool further includes one or more passive flow control mechanisms to mitigate a mean flow of the water induced by the movement of the at least one foil in the direction along the side wall.

A wave-forming system includes a channel having a water inlet and a water outlet for directing water from the water inlet and the water outlet. The channel has a side wall and a bottom surface profile that slopes downward toward the water outlet and the side wall. The system also includes a back pressure barrier positioned in the water outlet to introduce a back pressure to the water flow inside the channel to continuously form waves across the channel.
