One Design Racing
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 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.
In the late 30’s C. Raymond Hunt designed the 110, one of the first boats made of marine plywood. The 110 was a flat-bottomed, double-ended, 24-ft. splinter that was the first of the semi-planing hulls. It was light, easy to care for and inexpensive. Ray designed the Concordia Yawls in 1939. It seems safe to say that to this day Concordias have given more pleasure to more owners and won more important races than any other boat of similar type. After the war, the 110 was followed by the still-popular, larger 210. His 5.5-Meter “Minotaur” captured the Olympic gold in Naples. In 1963, Ray Hunt sailed his “Chaje II” to the 5.5 World Championships. He developed the 13-ft. Boston Whaler in the mid fifties. Thousands have been built and the design has changed little through the years. His most significant contribution to powerboats, however, was the development of the deep-vee.
