Subject: Removing Dutchman Fairleads on Main

The previous owner had the sailmakers install fairleads (round discs that penetrate the sail cloth) for the Dutchman Sail Flaking System. These have never been used because we have a stack pack and the control lines for the Dutchman system were never installed. Over the past couple of years the plastic fairleads have fallen off, leaving multiple holes for each attachment point in the main sail. What is the best way to secure the sailcloth where the 15 fairleads are missing. Should I sew on dacron patches, sew on ripstop, or is there a better solution?
Thanks!

You should create attactively shaped Dacron patches and sew one to each side of the sail over the holes. The patches should be about 1/2" larger all around than the area to be patched. Use basting tape #659 to stick the patches on prior to sewing.

Does Sailrite sell round dacron patches? Should I use the same weight as the main sailcloth or something lighter? I have photos of the holes if that helps.

We do not sell round patches but you can easily cut your own. You might want to do diamonds instead because they are much easier to sew around :)
 
Use 5 oz Dacron.

The sail is made with a High Aspect 8.62 oz. dacron. Should I still use 5 oz for the patch? Do I have to worry about the direction of the sailcloth for the patch?

Hi Wild Goose:

 

As the patch is stabilizing the rip and not replacing that section, 5oz patch material is just fine.  In fact, a heavier patch will create an aerodynamic bump, decreasing the efficiency of that part of the sail.  Direction of the weave should not matter.

 

I hope that this helps.

This is what I ended up using, and it is working great. I used the Insignia Adhesive Backed UV Dacron 10" (Item #721), cut in diamond shapes (sized to match the diamond shaped reinforcement patches used on the reefing grommets), and I did not sew in place (difficult to get under the machine, and after one I decided against sewing). Since then, we have been offshore for 10 days, with winds over 35kts, storms, etc. and every patch is 100% in place. Because the patches are reinforcing the holes left from the dutchman fairlead removal and not a rip, I'm not concerned if one does happen to come off. I have some pre-cut onboard and ready if I need a replacement. Hope this update will help someone else with a similar situation.
