Classes which are not development classes are usually referred to as "One design". The idea is that One Designs provide a fair and level playing field for even competition, whereas Development Classes drive boat speed and technology forwards. The first one design was the Water Wag designed by Thomas Middleton, which first sailed in Dublin Bay in 1887. The class is still sailed today, well over a hundred years later. 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. This design expanded to Holland, Netherlands, Germany, France, Ireland etc. and further afield.
