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.
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.
