The tail velcro on my old Prophecy failed after seven years of abuse. See photos.

Any advice on a no-sew repair? I don't really care what it looks like. I assume I'll add another layer of something, but what do with just glue?

The spine just poked through, there's no other damage to the area. The knock broke and create a sharp edge, I think. Should have had an end cap on it.

If you're really determined not to sew you could try joining the tear with superglue, tape it together first then glue like you would do with a sail tear.

However it really isn't difficult to sew on a new piece of velcro, or at a pinch put some insignia tape on the back and just sew the velcro to that if you don't want to touch the sail.

Make sure the spine tip has at least 2 vinyl end caps or maybe a standoff connector to spread the stress area.

Push the material back toward each side of the tear and then wrap 2 or 3 layers of gaffer tape (or whatever black tape you prefer.

Wrap the tape tightly without allowing the material to bunch.

You'll never see the repair from further than 5 feet away and the kite will fly the same.

Prophs aren't going to alter their balance much when you add 5 or 10 grams of material to the spine area.

Use adhesive insignia tapes to cover front/back of the damage area and then hand stitched the edge of the insignia tape for added protection(optional). A vinyl cap on the end of the spine will prevent future damage. Also a few layers of adhesive insignia tapes over the vinyl end cap will increase the size of the tip of the vinyl cap and therefore spreading the load.

No Sew, No Glue, No gummy tape residue until you can get a proper repair.

Use an FSD Leading Edge Connector instead of a nock or endcap, the T shape should catch the remaining material, you'll probably have to stiffen it with a short piece of spar material.

Of course an APA Standoff Connector with  short piece of spar glued in will also work if you have one in the box already

Good advice all. Some of my kites have a kevlar patch in this area. Always seems overkill.

I think I'll super glue the tear then use a T of some sort to spread the force.

And I'll check things more carefully between newbie lawn darts...

I'd replace the broken parts sewing new ones. This is how I'd proceed: I'd unstich and cut off the velcro keeping the dacron, than I'd sew a new dacron and velcro strip keeping the old broken dacron in the middle.
To prevent future damage I'd put a vinyl cap or better a standoff fitting at the end of the spine. Using the standoff fitting be prepared to cut off some millimeters of the spine due to the size of the fitting.
When sewing be careful to clear the trailing edge where the leech line is.
Don't worry about sewing, do some practice on spare parts, if you don't have experience, and then go with confidence  Wink  Smiley

Even hand stitching some velcro over that rip would work.
