What is a Sonar?Sonar Fleet 5Fleet OfficersPhoto GalleryWYC Race SeriesPast Race ResultsSonar Links

The Sonar is a 23 foot, high performance sailboat. Designed primarily as a yacht club day racer for all ages and skill levels of sailors. The Sonar is a one design keelboat that has something for everybody.  It is a unique design that combines features found in no other sailboat in the  world.  It is sleek, powerful, stable and exceptionally fast.  Best of all, Sonar racing is supported by an active class association, with more than 600 boats having been built since 1980.

Although a high performance racer, the Sonar is also a comfortable day sailor, just right for getting the entire family or friends on the water together.  With its 11 foot cockpit, angled seatbacks and plenty of leg room, you can easily take 8 friends along!  No other boat of this size (or even much larger) can make this claim.

Builders
Ontario Yachts, located in Oakville, Ontario, Canada, is the North American builder of Sonars. The company produces the Etchells 22, Ideal 18, Albacore, International 14, and Optimist dinghy, many of which have won North American championships.

Sonar Yachts Limited, located in the Isle of Wight, England, is the European builder and distributor of Sonars. The boat is a relative newcomer to Europe and is gaining popularity.

General Construction
Hull Hand laid up woven fiberglass with coremat coring for added strength and impact resistance. Each boat carefully crafted to meet one-design rules. White gelcoat standard; custom hull gelcoat colors and bottom paint optional.

Deck Fabricated as one-piece insert; includes three seat storage lockers. Two bunks (and space for a small Porta Potti) in lockable cuddy cabin with hatchboard. Extruded aluminum toerail bolted thru deck and hull flange.

Cockpit Huge 11'6" self-bailing cockpit with full-length seats, angled seatbacks. Seats 8 adults in comfort. Adjustable mainsheet traveler amidships.

Keel 900 pounds of cast lead, deep fin design. Narrow, with advanced foil shape for superior windward performance. Optional sling available for hoist launching.

Rudder 2" thick, very high-aspect and deep. Balanced design and large area provides excellent control and manueverability, even under spinnaker in strong winds. Inboard hung for protection and to retain the same light feel at all angles of heel. Laminated curved tiller.

Rigging Bendy tapered aluminum mast. 75% fractional rig is responsive, makes sailhandling easier. Elliptical mast section is keel stepped. Swept spreaders, adjustable backstay and moveable mast blocking at the partners permit fine tuning. Running rigging is Dacron and Spectra, cut to length and fitted for each application.

Sails Large Dacron mainsail and 100% jib, legal for class racing. Combination of larger main and smaller jib is easier to handle when tacking. Standard cunningham, outhaul, traveler controls and jib leads provide complete sail-shaping ability. Spinnaker and tapered aluminum pole available.
