I have never used it in marine, but plumbing uses TEF all the time, and it works well. It's worth remembering it took a long time for the corrosion to occur the first time, and any solution you apply will likely be effective in preventing it or slowing it down now.
That’s what I needed to hear, thanks 🙂

But I do have a small pot of TEF GEL that should be enough. According to the video below it's the right thing, what do you think?
How bad would it be to skip the butyl tape and just apply the TEF GEL? I'm not planing to sail this boat other 20 years anyway... And to sell it I'd probably swage those wires anyway.

I have used tef gel for years
it is superb as a barrier to reduce galv. corrosion
i suggest you don't use your fingers to spread the product like the man in the video
it is nasty stuff and while not caustic - probably not a good idea to use like that. i always wear disposable gloves and use it after dry fitting everything

The last couple of times sailing, I notice my bow foil acting funky - weird bending going on. Doing some winter maintenance, I noticed the thimble for the gull striker had compressed. It is a 3/16" sailmaker thimble. I do push the boat hard, just didn't realize how hard. Tried to post a pic, but it wouldn't stick.

Andinista,
Given your corrosion issue, as a former Nacra 5.5 owner, if you have not yet, I would suggest you inspect the front beam at the inner ends where the dolphin striker horizontal support bolts to the beam (3 bolts per side). By boat had corrosion there and I put small plates inside the beam to improve the structure where the corrosion had weakened it.

Thanks Patrick, i will. Still haven’t done much, I will report whatever I do
Hi!
After quite a while I repaired my bowfoil, here are the pictures.
Conclusions:
* I seriously considered to make double bridles instead, but then realized that I like to roll the jib on the forestay (even without roller furling), so I didn't.
* I will seal the rivets and plates edges to keep water away
* I love Tef-Gel
* There is little room for the plate that I added. I had to press the foil with my foot to bend it a little bit to be able to connect again the wires at both ends

Anybody has been there? Any advice will be greatly appreciated. Thanks!
You did a great job on the repair. I use Tuff Gel or LanoCote for corrosion inhibitors. It's a shame that Performance didn't care to insulate these foil parts. I have seen and repaired quite a few of them.
