Designed by Tony Castro, the SB20 is a British-built strict one-design 6.15m keelboat conceived as a wide appeal, affordable, competitive sportsboat for teams of three or four sailors. It is also, arguably, the most successful sportsboat in the world with 800 owners competing regularly in a programme of exciting local, national and international events.

Originally known as the Laser SB3, the SB20 continues to deliver on its pioneering promise: a boat that is fun, fast and easy to sail by anyone of any age; the best value-for-money sportsboat in the market.
