A great way to introduce people to riding behind the boat without a steep learning curve. The HO RAD+ (Round Aquatic Device) allows anyone to participate in a day behind the boat. Simply put the handle in the handle hook, and you can sit, stand, or kneel, and away you go. The riding possibilities are endless. Amazing 4" thick drop-stitch construction results in the most durable inflatable that can be inflated to optimum rigidity, up to 20 psi. An additional layer of reinforced PVC provides even more strength. Machined EVA traction pads provide excellent grip, and soft nylon handle ensures better holding power and comfortable steering. Comes with a "device-specific" hand pump and PSI pressure gauge. 400-lb. weight limit while disc is floating stationary in water. Weighs 9.8 lbs. 4' diameter.
