Kneeboarding (towsport)


Kneeboarding is an aquatic sport where the participant is towed on a buoyant, convex, and hydrodynamically shaped board at a planing speed, most often behind a motorboat. Kneeboarding on a surf style board with fin(s) is also done in waves at the beach. In the usual configuration of a tow-sport kneeboard, riders kneel on their heels on the board, and secure themselves to the deck with an adjustable Velcro strap over their thighs. Most water ski kneeboards do not have fins to allow for easier surface spins. As in wakeboarding or water skiing, the rider hangs onto a tow-rope. The advantages of kneeboarding versus other tow-sports seems to be an easier learning curve and a sense of being closer to the water when falls occur.

Kneeboards were first produced commercially in the 1950s. While they were not widely popular at first, kneeboarding had become widespread by the mid-1950s. Today, kneeboarding remains popular, with sales of about 100,000 units per year.

As waterskiing gained popularity, riders also experimented with kneeling down on round plywood discs. Others tried kneeling on surfboards and some used purpose-built kneeboards designed specifically for riding waves, but the water ski kneeboard did not emerge as a product until the 1970s.

The first commercially available water ski kneeboard was Knee Ski, co-invented by Mike Murphy and Bud Hulst in 1972. Hulst had a background in surfing, manufacturing kneeboards for wave riding under the name of El Paipo. Murphy had been a professional show skier. The original Knee Ski was made from molded fiberglass, like a boat hull, and was neutrally buoyant. Each Knee Ski had a flat neoprene pad covering the entire deck, and a Velcro strap.

In 1973, John Taylor, a former Knee Ski employee, decided to make and sell his own boards under the name of Glide Slide. Taylor took a new approach, blow molding a plastic shell and filling it with foam. Unfortunately the teardrop design was unstable, and Glide Slide faltered as the 1973 oil crisis slowed the water sports industry.

Danny Churchill, quarter mile speed ski record holder in 1974 and former Glide Slide employee, bought the company in the wake of the oil crisis. Churchill redesigned the Glide Slide to make it more stable and renamed the product Hydroslide in 1976. Churchill is most commonly known for popularizing the sport through advertising and promotions in the newly released full color water ski publications of the late 1970s and early 1980s.
