Yes. There are height and weight requirements specified by the engineers who created these attractions to ensure your safety. The height and weight requirements are as follows: Slides - 48" tall and max weight of 250 lbs, Body Boarding - 42" & Flowboarding (stand-up) - 52". There is no weight restriction for the Flowrider. Life jackets or any sort of flotation device may not be worn or used on the Flowrider or the slides. All Flowboarding (stand-up) riders must sign a waiver in the Surf Shack. Parent/guardian permission is required for youth under the age of 18 to participate on the Flowrider in the stand-up position. You may do so by signing the back of the Flowrider waiver.
