First fix applied with Gorilla Repair tape. Man that thing is sticky, so sticky that I had a hard time even pulling it off the roll Very Happy !

It's slightly stretchy and quite thick. It's pretty install friendly where there's not really a need to push the bubbles out. Very sticky but still can be peeled off when installing, not so sure after a few days Very Happy !

EDIT: First wet session, the tape disappears and is nearly see-through, sweet!

EDIT2: It seems that the tape has slipped a bit and now the panel is loose where the crack was. I'm unsure whether to cut it and join it back together? There's a lot of tension there landing backloops or getting washed.

Anyway, thanks for the recommendation, there are several clear tapes by Gorilla and the one I used is this one:

I got some slack in the area of repair and blame the lack of overlapping width. So I cut up where the old tear was and pulled it together. I even overlapped some sail material near the center probably where the tear started.

Is some sail stretch to be expected around the tear area and should it be overlapped when repairing to retain the most tension?

I added reinforcement pieces sideways of the rip to minimize the tape from sliding.

Hey Manuel,

It seems to me that cutting and overlapping would create even more
tension and stresses (and change the warp slightly) on the already
weakened area in the panel you're taping. To me that seems worse than
having a small slack area, and more likely to have the tape glue deform
and slide under that tension. Hope I'm wrong about that.

Ok I understand. There seems to be some unavoidable slack that develops over time. I guess the idea of taping is to prevent the tear from spreading and it's natural that tension will be lost in the area. When overlapping I simply held the material in place as it laid flat on the ground, I simply held it down with no batten or sail tension.

This part of the sail lays on the boom when powered up. I don't think it's an issue either way just learning on to tape x-ply Very Happy !

In many cases... a taped-up sail can still provide MANY years of fun sailing!
This sail is from 1999... but the vid is just a few years old.

And still providing fun... i still use it for shortboarding and longboarding. But... It's also one of the sails I use now for windfoiling. These pics are from the last 2 months.
Again taped up sails can provide years of fun. And they look cool. This sail has character... I get more attention using this, compared to most my sails, haha!

My rule is: When the weight of the tape equals the weight of the sail, time to purchase a new sail. Let it go...let it go....

Greg, you have a ways to go before you are there...

Right, haha!
This 7.9m 3 cam 1999 race sail is still way WAY lighter than a newer race sail.
