Sonars
The Sonar was designed in 1979 by Bruce Kirby, designer of the popular Laser dinghy. Since then, over 700 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.
