A portable water sports environment is provided. The environment includes a mat positioned on a liner. The front end of the liner may be positioned proximate to a body of water. The back end of the liner may be positioned distally to the body of water. A spray nozzle positioned along a front end of the liner may spray water from the body of water onto the mat and toward the back end of the liner. The environment may a ballast positioned on the top surface of the liner and spaced from the mat. The mat, the top surface of the liner, and the ballast may define a trench that extends away from the back end of the liner and toward the front end of the liner. The trench may guide water received from the spray nozzle toward the front end of the liner and into the body of water.

To provide a surfing wave-making apparatus that is capable of making the so-called tubular plunging breakers which are suitable for surfing, and which have continuous crests ranging from a collapse stage to a stage immediately before collapse. The present invention comprises: a container body 110 that is open at the front thereof, is equipped with at least a bottom part, and is capable of trapping water in part of the inner space thereof; and a moving track 120 that allows the container body 110 to travel thereon and that is equipped with a slope surface track 121 and an in-pool track 123. The container body 110 falls along the slope surface track 121, plunges into water of the pool as a result of free-fall motion, and travels on the in-pool track 123 in the container body 110 decelerates, only the water held inside is thrust forward in the form of an isolated traveling wave 202 so as to produce a plunging breaker suitable for surfing.

Soft-tipped pole designs and methods for their use on pavement are disclosed. The soft, gripping pole tip can slow down a roller skier or skateboarder by slowing down the rider directly and by providing increased rider stability during breaking. This is accomplished by the rider pressing one or two pole tips against the pavement, with or without the use of a fulcrum point for increased leverage. The soft rubberlike tip has a large surface area that provides durability as well as variable levels of frictional force imparted against the pavement. The fulcrum for the pole can be the user's arm or leg as well as fulcrum element fastened to the rolling device.

A wave generating system can include a water channel for creating a flow of water to produce a standing wave. A water return passageway can circulate the water back to the inlet of the water channel. One or more pipes can extend under the water channel for circulating the water. A water storage chamber can be positioned below the water channel. Water can be stored in the space between the one or more pipes, and the storage water can be isolated from the water being circulated in the system. The system can produce a hydraulic circuit with hydraulic continuity so that water can be efficiently circulated through the water channel and water return passageway. The system can be modular.

The invention relates to a surfing installation (10, 10A, 10B) for generating a surfable wave (60), comprising an inclined ramp (50) to the upper end (51) of which water flows via a water inlet (46), which water is accelerated on the ramp (50) to a first flow speed, the lower end (52) of the ramp (50) leading into a region (30) having a lower second flow speed relative to the first flow speed, and a standing wave, in the flow direction, forming in the region (30) as a result of the water flowing at the first, faster flow speed striking the water flowing at the second, lower flow speed. A further functional area for the surfing installation (10) for one or more surfers (80) is achieved, according to the invention, in that at least two walls (506, 508) that define at least one flow channel (504) are arranged in the region of the water inlet (46) and/or of the ramp (50), which walls are movable in rotation and/or in translation, transversely to the flow direction of the water, by means of at least one drive (5046), in order to generate at least one traveling wave (60) that travels transversely to the flow direction.

Devices and methods for generating surfable waves in a pool. Waves are generated by removing support, at a progression of areas at the bottom of the pool, for the water in the pool and causing rapid downflow at a progression of areas at the bottom of the pool.

A training device for teaching a user how to snowboard is disclosed. The training device includes a telescoping unit, a hinge unit, a locking mechanism, and a handlebar. The telescoping unit includes telescoping sections that are slidably coupled with one another, with a first end of the telescoping unit including a grip. The hinge unit is coupled to a second end of the telescoping unit. The locking mechanism is adjustably coupled to the hinge. The handlebar is coupled to the hinge a center region thereof such that opposing longitudinal distal ends of the handlebar are spaced from the hinge unit. Further, the handlebar is rotatable between: a first position, where the handlebar extends substantially perpendicular relative to the telescoping unit, and a second position, where the handlebar extends substantially parallel relative to the telescoping unit.

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.

Improved balance boards feature a combination of components that increases versatility and challenges with use. An elongated deck has a lower surface with a lengthwise recess configured to receive ground-contacting apparatus enabling a user to practice balancing on the board while standing on the upper surface of the deck. The ground-contacting apparatus may be balls of different sizes, rolling pins, or inserts with rollers, wheels, or non-rotating skateboard trucks. The inserts may have a peripheral edge that corresponds to the peripheral outline of the recess, and may be held in position using hook-and-loop fasteners, magnetic elements, or fasteners that extend through the insert and the deck.

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