The Ontario Sonar is a 23foot keelboat that serves as a masterclass in Bruce Kirby’s "cleanandsimple" design philosophy. Introduced in 1980, the Sonar was born from Kirby’s desire to create a highperformance racing vessel that didn’t sacrifice the comfort and safety required for family daysailing. Built primarily by Ontario Yachts in Burlington, Ontario—under the direction of Dirk Kneulman—the Sonar became a staple of the North American sailing scene. It is perhaps most distinguished by its massive, selfbailing cockpit and its legacy as an International Class, having been selected for use in the Paralympic Games from 1996 through 2016 due to its exceptional stability and accessible layout.
