Windglider
For the 1984 Los Angeles Olympics, the Olympic board choice was between the original Windsurfer One Design manufactured by Hoyle Schwitzer and the Windglider designed and made in Europe. The Windglider was chosen late in 1983 based on it being more 'one design' as the Windsurfer was made of polyethylene and its rocker could be easily changed with heat and weight on a daily basis.
