You can surf it, use it as a kneeboard, stand up like a wakeboard or a set of skis. A front handle hook will hold the rope while you get up to speed, making it easy to use for any age. Roto-molded board has a thick EVA pad with arch support and 2 removable 3.6" (9.1 cm) surf fins. The Thing Kneeboard measures 59" (151 cm) in length.
