The RAD (Round Aquatic Device) and FAD (Fun Aquatic Device) are inflatable towables, constructed with drop stitch technology. The drop stitch allows H.O. to create inflatables that can be inflated to optimum rigidity while delivering the most durable inflatables they've ever offered. The technology is achieved by joining two pieces of support fabric together with thousands of fine polyester thread lengths. Each thread is spaced evenly and all threads are the exact same length. An airtight coating is applied to the top and bottom of the support material. The RAD and FAD are capable of achieving levels of pressure equal to 20 PSI (Pounds per Square Inch).
Before wakeboarding was invented, watersports pioneers of the 1960's experimented with objects to ride behind the boat. Some of the more successful riding devices were wooden discs. Dad would take a piece of plywood to his woodshop and cut it into a circular shape. The family would take turns 'discing' in between water ski sets. It was a great way to introduce people to riding behind the boat without the learning curve associated with waterskiing.
Fast forward 50 years, and H.O. combined the nostalgia of the past with the advanced materials and modern construction methods to give you the new RAD discs and FAD boards. The RAD takes the place of the wooden discs (no slivers here!), and the FAD can be used like a kneeboard or wakesurfer.
True story - Scott's Dad used to ski on a homemade wooden disc, not to mention canoe paddles and everything else he could create or get his hands on!
