Paralympics Class

The Sonar is a 7 m (23 ft) one-design keelboat for three to five people. It is bermuda-rigged, with a large mainsail and a 100% jib. The class is recognised by the International Sailing Federation.

The Sonar showcased disabled sailing at the 1996 Paralympic were the sport was a demonstration event with just the Sonar. Sailing and the Sonar as the equipment for the three person keelboat have been in every subsequent Paralympics. When being sailed by disabled it is crewed by 3, and sailed without a spinnaker. Instead, when running downwind a whisker pole is used to hold the jib out to windward for maximum exposed sail area. The Sonar is well suited for handicapped sailing because of its large cockpit making adaptations easy.

The Sonar was designed in 1979 by Bruce Kirby, designer of the popular Laser dinghy. Since then, over 800 boats have been built. Most of the fleet is in the USA, with smaller fleets in Britain and Canada. Since its adoption as a Paralympic class the Sonar has spread to many other countries as well.

The Sonar was inducted into the American Sailboat Hall of Fame in 2004.

History

It started when Bruce Kirby's home club (Noroton Yacht Club, Darien, CT USA) couldn't find the right boat to get their members involved in club racing; fewer and fewer of its members were participating.

They studied a great many existing classes of boats but all were considered too expensive, too slow, too demanding to sail, or just plain uncomfortable. So Bruce was asked to design a new boat specifically to meet the requirements of a club racing one-design keelboat fleet.

It had to be exciting to race, but easy to handle by sailors of all ages, strengths and skill levels. It had to be a really good day sailor, spacious and comfortable to sit in all day long. It had to be trailerable, plus easy to launch for wet or dry sailing. Plus a safe, well behaved training boat to help teach new sailors how to sail and have fun doing it. Finally, it had to have a good but uncomplicated set of class rules.

The result was the Sonar. The Noroton Yacht Club got every thing they wanted and more. And the Sonar has been greeted with enthusiasm by individuals and clubs all over the world.

Disabled World Championships

As well as open competition the Sonar has been used extensively for disabled sailing. The boat is exactly the same but adaptation are fitted to the boat to aid the crew who are not permitted to hike and the spinnaker isn't used. Throughout the International Association for Disabled Sailing the following ISAF recognised World Championships specifically for disabled competition have happened.
