History
At the I.M.Y.R.U. General Meeting at Dunkerque in 1982, it was resolved to adopt the IYRR and IYRU Measurement Instructions and to follow the IYRU Constitution and Regulations as closely as possible. For the next eight years a lot of very hard work was done by the I.M.Y.R.U., particularly by its then Chairman, Norman Hatfield, to get Model Yachting accepted into membership of the full-size governing body, the International Yacht Racing Union (IYRU). This work culminated on 1st May, 1990 when the I.M.Y.R.U. became the Model Yacht Racing Division of the IYRU (IYRU - MYRD). In its turn, in August, 1996, the IYRU changed its name to the International Sailing FederationInternational Sailing Federation
