IRC Congress looks to the future
Another successful annual IRC Congress meeting was held in early October in the popular sailing venue and race destination of St Malo on the northern French coast. Forty delegates from as far afield as Japan and the USA came together to talk about the International Rating Certificate (IRC) racing around the world, technical development and ideas on encouraging participation in yacht racing generally.
In 2018 there is the exciting prospect of the IRC European Championship combined with the RORC’s Commodores’ Cup in Cowes in June, closely followed by the joint IRC and ORC Hague Offshore World Championship in the Netherlands in July. These events set the high standard for IRC racing in 2018, along with the major offshore classic races that continue to be scored using IRC.
