We used a product like this
on recommendation from our local West Marine
to repair rips on both the jib
of our Hobie cat
(Dacron material). I forget the specific name of the brand we used. That was seven to eight years ago and the tape was still holding up very well up until Hurricane
Sandy caused a tree to fall on the boat
. It also completely stopped both rips from growing.
To apply it, we removed the sails, and cleaned the area of the rips on both sides with a sponge, water
, and a small bit of dish soap. We then rinsed and dried the area thoroughly. When applying the tape, we made very sure to get it very flat, and cut it to extend past the rip for two-three inches on each side. Be careful when applying it, as it's very gummy and the less you can handle it the better.
After the repair, the sails were routinely doused in water
as there's no point sailing a Hobie if you don't tip it over. It was extraordinarily durable. The jib
tape repair worked great with the roller furling
, no adhesive
or anything leaked out to bind the sail together or anything like that while it was rolled up.
I'm not sure this experience will translate to larger yachts and different sail materials, but it worked great for us and I have no doubt it would continue doing so if it weren't for that damned hurricane
. At least we got a high performance flagpole out of the wreck.
