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. Grandpa 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.

This "disc boat tube" was a great way to introduce people to riding behind the boat without the learning curve associated with waterskiing.

50 years later, HO has combined the nostalgia of the past with the advanced materials and construction methods of today to give you the new RAD discs. Round Aquatic Devices (RADs) allow anyone, regardless of skill level, to participate in a day behind the boat.

Everyone can get up on the 5’ RAD! You can put the handle in the soft EVA handle hook, sit, stand or kneel, and away you go. For a more advanced ride; go with the 4’ RAD or the even smaller 3’ RAD disc.

The riding possibilities are endless, opening up a world of pure imagination on for your friends and family. Fun for all ages, the RADs are guaranteed to turn some heads on your lake this summer.

RAD & FAD Technology

Drop Stitch is a pretty amazing material we're using to create the RADs and FAD. This material allows us to build inflatable items that can be inflated to optimum rigidity while delivering the most durable inflatables we've ever offered.

This innovative material is called Drop Stitch and 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.

Next an air-tight coating is applied to the top and bottom of the support material to ensure an air tight seal. The result is Drop Stitch Construction. Drop Stitch construction is capable of achieving levels of pressure equal to 20 PSI (Pounds per Square Inch).
