Severne blade. landed onto of my sail. harness hook made a minor dimple(stretched ) into the window. no creasing, or puncture. wondering if taking a hair dryer and heating it up would make the material shrink back to position....even just a little ? Is there any fix ? had this happened to other sails...I usually just live with it. doesn't affect the sails performance . just a cosmetic issue.

I've heard of ironing it, hot air gun etc but as ugly as it may be I would just leave it. Probably make it weaker trying to fix it

I've wondered this too, also dented my 5.0 Blade in a similar way but I've never done anything about it.

A lot of plastics will return to their original shape with the correct amount of heat applied. However, getting that right balance can be the difference between a great job and, well, not so great

Fill the dimple with Six10 then leave it for at least a week in a room with a fan on.

LOL....... same for me got catapulted head first into the panel above the boom on my new 5.3 bum n jump sail first time out, probably only an hour into the session leaving a sizeable dent from my helmet, so thanks Kato might try the same thing

You would still have the bulge on the other side though unless you ground it down.

No one is thinking of the obvious , the sail would be bigger now , you would need to go down a size.

Not if you put your harness lines in a different place to everyone else........

Dimples are fast, just look at golf balls (-;

I landed in the foot of my brand new 7.5m Turbo. I was so relieved to see no damage to the sail..I realised later I'd damaged my ribs instead... Still, they were good after
5 weeks..

Well.some of you probably already knew this. I tried the boiling water . It really didn't do much. I think it brought it down a bit. If i was to give it a percentage.maybe 15-20% improvement . Perhaps the water was not boiling..I was lazy and got the hot water from the Kureg machine. Anyway. I will leave it as be.not that big of a deal.

I was gonna take a heat gun to it..but I could see my self melting a hole through the sail..so I figured I better not.

Better safe than sorry. Thanks for letting us know, I saw the dimples in my big blade this morning and I just figure they're going to be staying there.

Wise not to take extreme measures. A hole in a sail is slower than a dimple. Besides, this young lass had dimples and it didn't seem to hurt her career. en.wikipedia.org/wiki/Dimples_(1936_film)
