The A-Class Catamaran is the fastest single handed catamaran in production. Due to the developmental nature of the class, high tech materials such as carbon fiber are incorporated in the designs which are updated yearly keeping the class on the edge of technology and performance. With the development of foils, A-Class catamarans are able to maintain and exceed speeds of 24 knots.

In the United States, there are over 150 active A-class members who race at local clubs across the country, and travel to national level competitions which attract 50+ competitors.
