Sonar Parts

West Coast Sailing is your source for Sonar sailboat parts, rigging and accessories. The 23-foot Sonar is popular for its combination of comfort, speed, and ease of handling. This trailerable Bermuda rig, sailed by a crew of 3 to 5, seats up to 8 people and has a deep keel for stability. The Sonar's generous cockpit appealed to both disabled and able-bodied sailors. It became Europe's first Paralympic sailing class in 1996. The American Sailboat Hall of Fame inducted the Sonar in 2000 as a boat that is friendly to new sailors, exciting for club racers, and fun for day sailing. Shop Sonar sailboat parts, rigging, and accessories today with rigging guides, technical information, extensive selection, and fast shipping to help you get back out on the water.

Rigging Diagram

Use the diagram below to reference Harken part numbers to appropriate application on your Sonar sailboat. Parts recommendations are offered as a guide for common applications.

Jib Halyard Fine-Tune

This high-power jib halyard fine-tune allows you to tension the luff as the wind cranks up. When you need headstay sag to power up the jib in chop and light air, the fine-tune allows quick control over headstay tension, making it easier to insert mast chocks.

Mainsheet Bridle

Upgrading to a bridle can make your system self-tacking in 10-20 knots and downwind while reducing the adjustments needed in other wind ranges. Simply add a second low-friction Harken 2731 car and use Spectra® strops about 28 inches long. The length of the bridle straps is key so you can sheet in hard to center the boom without closing off the leach.

Jib Sheet Coarse/Fine-Tune

This hand-trimmed 6:1 system has a gross-trim for speed in quick tacks and a fine-tune for precise, fingertip control in any breeze.
