Abstract

A water sports apparatus, for simultaneous practicing of a number of types of water sports, being a container having an inclined floor surface and closable lower supply nozzle. Water shooting upwardly over the floor surface flows over an overflow into a supplementary pool which is subdivided into two regions, between which regions is placed a grate, and preferably, on the downstream side of the grate, a backflow valve. On the end of the inclined floor near the supply nozzle is placed an elevated water container, the water from which enables starting of the supercritical torrential flow, until a water quantity necessary for circulation and having sufficient velocity is returned through a return line from the region of the supplementary pool farthest away from the overflow. The region of the supplementary pool near to the overflow enables the athlete to exit from the apparatus without influencing the supercritical torrential stream in the water container. The return line is preferably an open trough, which can flow along an arbitrary pathway through various regions of a recreational facility, and return to the elevated container, whereby in the trough, and pools communicating with it, varying flow conditions can be attained.
