Custom Replacement Heastays
Harken installations will sometimes require shortening or replacing the headstay because of the added length of the toggle at the bottom. Often customers will replace the headstay at that time, especially if the rigging is more that a 10 years old. We can help you with this.

To replace your headstay when installing your new furler call us with your "pin to pin" dimension. (The dimension between the center lines of the clevis pin holes at the mast head connection and the stem fitting at the bow of the boat (with turnbuckle in normal adjustment). Also provide wire diameter and pin sizes both top and bottom. Custom headstays take about 7-10 Days to make.

(Headstays are sold with
furler purchase only)
