Kite Boards History part two

In the late 1970s the development of Kevlar then Spectra flying lines and more controllable kites with improved efficiency contributed to practical kite traction. In 1978, Ian Day's "FlexiFoil" kite-powered Tornado catamaran exceeded 40 km/h.

Through the 1980s there were sporadic and occasionally successful attempts to combine kites with canoes, ice skates, snow skis, water skis and roller skates.

Through out the 70s and early 80s Dieter Strasilla from Germany developed parachute-skiing and later perfected a kiteskiing system using self made paragliders and a ball-socket swivel allowing the pilot to kitesail upwind and uphill but also to take off into the air at will. Strasilla and his friend Andrea Kuhn/Switzerland used this invention also in combination with surfboards and Skurfs, grasskies and selfmade buggies. One of his patents describes 1979 the first time an inflatable kite design for kitesurfing.

Two brothers, Bruno Legaignoux and Dominique Legaignoux, from the Atlantic coast of France, developed some kite designs for kitesurfing in the late 1970s early 1980s and patented a inflatable kite design in November 1984, which has since been used by many companies to develop their own products.
