RS21 – Keelboat sailing the RS way




The RS21 One Design is a modern keelboat designed with corinthian racing at its heart – keelboat racing the RS way.  Finished and completed so you can enjoy close one design sailing without the complex choices. The powerful rig and distinct chines are balanced by well-mannered boat handling and an ergonomic deck layout to ensure everyone sailing has a key role to play and yet ease of use. For those passionate about our planet, the RS21 was developed with sustainability at the core of its design not only in terms of materials but also the carbon footprint of the supply chain, a reduction in single use plastics and efficient logistics. The RS21 International Class is going from strength to strength, with fleets growing over three continents and a national and international racing calendar that is escalating each year. Corinthian sailing, epicly close racing and a class built around removing the arms race, the RS21 is the future of keelboat racing and everything you’d expect from an RS racing class.

It’s a very good boat. It planed in 11-12knots, very responsive to roll tacking, roll gybing. Very responsive to rig tune, sail tune and crew weight. It’s a good boat, good platform, a lot of fun!

I think they’ve hit their marks on everything that I could see, and after 10 races on the boat, none of us were beat up at all. I’d jump on one of these little beauties anytime.

Loved the boat and great to get back into some proper one design racing again. I found the RS pretty tweaky upwind: really rewarding accurate steering and trimming: just how I like it! The racing was super close: the last cross often deciding the difference between first and fifth place around the windward mark. And downwind was equally interesting, with plenty of angle options through the range of conditions. The last run, once the wind fully filled in, had us all grinning all the way to the finish!

While it’s a keel boat, it still handles an awful lot like a small dinghy. We were surfing it downwind.
