The SB20 is a one-design class of sailboat commonly used for racing. Marketed and distributed by Sportsboat World, the boat was designed by Tony Castro and launched in 2002. The SB20 was originally called the Laser SB3, and was marketed and distributed by Laser Performance under licence from the designer. This licence ended in 2012.
The boat is an open keelboat and is designed for racing with a crew of 3 (or 4) whose maximum weight must not exceed 270 kg. With a high aspect ratio keel with a very high ballast ratio the yacht is very stable, but also quite fast due to the substantial sail area. This makes for highly tactical upwind sailing and fast and exciting downwind sailing.
The SB20 is unique in that it does not allow hiking, using a small stainless steel bar to prevent hiking by the crew, this allows competitive crews of all shapes, sizes and ages. The boat is a strict one-design keelboat that makes for close racing.
There are over 800 boats worldwide, sailed in over 20 countries. The majority of boats are located in the United Kingdom, Ireland, Portugal, France, Australia, Singapore, Russia, the Netherlands, Germany, Abu Dhabi/Dubai and Italy, and the Class has attracted considerable support.
