Dinghy sailing
Dinghy designs are often called "classes"; these classes are usually either one design or development. The idea is that One Designs provide a fair and even competition, but Development Classes make new faster and better boats.   The first International one-design class was the B.R.A. 12 foot dinghy which was designed by George Cockshott in 1914 for West Kirby marine lake near Liverpool, England. This design then went to the Netherlands, Germany, France, Ireland etc.
