The invention relates to a portable water ride having a trailer with a water catch basin built therein, wherein at least two pivoting supports are provided which can be deployed to an expanded position and stowed to a vertical position. When the supports are deployed, a flexible ride surface can be stretched between said supports to form an inclined ride surface upon which a sheet flow of water from a nozzle housing can be provided upon which water skimming maneuvers can be performed. A walkway on either side of the ride surface, as well as an entrance platform at the top of the ride surface, and other grated platforms, railings, etc., can also be provided.
