The Raja Muda Selangor International Regatta is a challenging offshore & inshore sailing race organised every year by the Royal Selangor Yacht Club in association with the RORC and consists of three overnight passage races, 260 miles in total, plus 3 days of harbour racing in Penang and Langkawi. The event attracts a large variety of yachts, from top class IRC1 racers to slow classic cruisers dating back over 100 years, all of whom had to cope with unpredictable weather and changing tactics during the 9 day mix of races past tropical islands.
