RS21 Class Association




Keelboat Sailing the RS21 Way

The RS21 is the ultimate one-design racing class. These modern boats have revolutionised keelboat racing. Sticking to the Corinthian ethos, sailors compete in identical RS21s; levelling the playing field and intensifying the competition. Success on the racecourse is determined by the skill and strategy of the crew rather than the difference in equipment.

The RS21 is rapidly gaining in popularity thanks to its emphasis on close, tactical racing. This fresh approach engages seasoned sailors with a dynamic racing experience while, at the same time, attracting a new generation to the sport. The boats are designed to be handled by sailors of varying skill levels. Everyone has a role to play and ease-of-use is part of the attraction. 

Fleets are building across the globe – the RS21 International Class Association covers four continents, but world domination doesn’t stop there… The International Racing Calendar is well organised, with a dedicated Class Manager at the helm. Partnering with RS Sailing and its worldwide network, the class is well-supported to deliver fantastic racing. Events are curated with a winning three-part formula: great venues, prestigious race areas and enjoyable socials.
