Itchenor Sailing Club is a sailing club located in Chichester Harbour which was founded in 1927.
The Sailing Club races every weekend from April to November with midweek racing for keelboats, as well as specific weeks for class regattas. A comprehensive programme is run for keelboat classes (National Swallow, Solent Sunbeam, X-One-Designs) and jetty dinghy classes (International 14, RSK6, RS800, RS200, International 420, Topper and Mirror). Open Meetings are held for most classes, including the annual Schools Week.
The Mirror fleet at Itchenor is the biggest and most active fleet in the country and possibly the world comprising just over 100 boats.
Junior Fortnight is an annual series of racing that takes place over a fortnight during the summer holidays. It has its own Committee that oversees the running of Junior Fortnight. As well as a racing programme which consists of ten to thirteen races in all, there is a social programme. The social programme includes two bops which occur on the first and last nights of the event, a talent show, themed parties, cricket matches and a prizegiving at the end of the fortnight.
The fortnight series, organised and run by Itchenor Sailing Club, sees competitors from neighbouring sailing clubs in Chichester Harbour, such as Hayling Island Sailing Club, West Wittering Sailing Club, Emsworth Sailing Club, Bosham Sailing Club and others.
Schools Week (also known as the Schools Championship) is an inter-schools sailing competition which is organised and run by Itchenor Sailing Club. It was started in 1953 under the name of 'The Public Schools Firefly Invitation Championships.' Currently the fleets include 420s, Fireflies and RS Fevas. Between 1997 and 1999 Laser Radials were introduced to the class but failed to catch on.
Competing schools have included Charterhouse, King's School, Canterbury, Magdalen College School, Oxford, Oundle, Portsmouth Grammar School, Sevenoaks, Sherborne, Tonbridge and Winchester College.
