The yacht 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. 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 majority of boats are located in the United Kingdom, Ireland, Portugal, Australia, Singapore and Italy and the class has attracted considerable support. There is a growing fleet in the UAE. In 2005 the SB20 became the second largest one-design fleet at the Cowes Week regatta with 66 entries. In 2006 it became the largest fleet with 89 entries pushing the XOD into second place, an accolade it held for two further years.
There are over 700 boats worldwide, sailed in over 20 countries. Growth in fleets internationally enabled the class to successfully apply to World Sailing for the right to host a world championship, the first of which was hosted in Dublin during 2008.
