C2 and Viper Owners

What's the failure mode? I'm the 2nd owner, so not sure if my '10 C2 was ever done. Anchors are rock solid, but...

They snap off inside the hull. Check with Jill or Goodall Design when they stopped shipping boats that had the issue. You'll be able to tell if yours have been fixed post delivery because there will be a 1 inch scar in the gelcoat around the chain plate.

PM me your email address and I'll send you Jim Boyer's guide on how to effect the repair.

I had heard of some kind of campaign to replace these, but have to admit I hadn't taken it very seriously. Not liking the idea of a sudden failure. Not sure when or if I'll have my boat in Florida this winter. Will send a pm.

Edited highlights or the repair:

then...

Finally..

Is that tang just a bent piece of stainless with a nut holding it on the threaded bit? Would have liked to see the new tang before it was installed.

No the tang is a machined lug with a drilled and tapped thread that screws down onto the thread shown in the third last image. I believe from Rehmbo that this detail might have changed as he describes his as more like an eye bolt.

Scarecrow, that is the old capricorn tangs, the C2 / Viper uses and eye bolt. this has nothing to do with that repair nor are there any forecast failures.

So what is the upgrade Jill and Robbie are offering to do?

changing metric eye bolts for imperial ones.. or so i have heard...

That is not correct. The eye bolts have been known to fail and are being swapped out for larger ones. The new ones may be imperial but that has nothing to do with the issue.

Jeff, I doubt your boat was been swapped out, email Jill and ask her to send you the hardware and the instructions I'm sure it's not that difficult.

That is pretty incredible dealer support...I have to say.

In my case its not their fault. I'm about 1200 miles from them and haven't had my boat in FL in a couple years (something I need to rectify this year!)

100% agree! To be honest it's the only reason I'm on a C2 instead of an Infusion.

I noticed a rust stain on the first few pictures showing the damage.

Wonder if that stain's appearance indicated some sort of crevice corrosion prior to the ultimate failure?

Yep! Steeplechase, Tradewinds and Charlotte Harbour is a great winter series. Plus there is that week long event in October 🙂

Infusion support has been fixed-Nacra NA is under new management. Our Mk. 2 is very well built and very quick.

My first though, as well. Good work.

I will certainly not claim to be an expert, but there are many people who believe exactly what you describe (rust is a warning sign of a deeper problem with stainless fittings).

Very wise of Jill to proactively manage this, in a very organized manner.

Thanks Sam! Ding I'll remember that <img src="<>/smile.gif" alt="smile" title="smile" height="15" width="15" />
To be fair it is the reason I switched to a C2 as well. Jill and AHPC really stand by their product as any manufacturer should.
Gunnar and I are committed to doing the same for Nacra.
The new shroud bolt is Nearly twice the size of the old one. It snaps with no notice (we nearly lost our rig but it snapped going into a tack so I saw it and aborted the tack before the rig came down). Other point is make sure it is perpendicularly pointing towards mast so it doesn't size load the tang.

I'm about positive your boat has not had this changed out.

Thanks for the heads up, guess this means I gotta head to Florida.

If you're not looking for an excuse to travel to FL, I'm sure we can knock that out 😉

Can I bring my viper to that party?

The bolts on my C2 are about an inch wide, they are from my memory larger than the bolts on Mac's 2009 Viper. Does this mean I already have the upgraded bolts?

are they the same size as the chain plates for the bridle. If they are bigger than the bridle then it's been upgraded.
