Ah, I see now that it's the front and back that give the supprt, not just wedged in on the sides. Thanks CG!

Correct the sides are supposed to be parallel.

I mentioned a similar issue with race fins to a board repairer and he recommended PTFE tape. I haven't tried it, but it may work?!

Back in 1996 my wife sailed my newly built slalom board into a pile of rocks on its first day on the water. She jammed the tuttle fin back and cracked the inside of the Chinook Tuttle box. Those boxes seem to have 2 walls, since she cracked the thin inside wall at the back, but the wider thick surrounding plastic was OK.

So, what I learned from that is:
- it is possible to crack the inside part of the Chinook Tuttle box, it's not as thick as the outer wall
- don't try fixing it by just greasing the fin and using that as a mold with chopped glass and epoxy. It was a bugger getting the fin out!

I think beefing up the front and back of the "fin" (mast) is a good idea. I'd try maybe using very thin plastic if I was going to use the mast and box together as a mold. Also, I wonder what would happen if you added a shim to the bottom of the box, so the mast bottoms out at the right depth? Adding more support from all directions can't be a bad thing.

Here is what my Spotz2 tuttle looks like after I repaired the ends. They had been ground away at the Spotz factory by someone who probably wanted them to fit easier but who has no understanding how much this weakens the Tuttle mount and allows the mast to pivot. My mast now fits perfectly in my board and not longer shifts around. Several of us here have had to do this epoxy repair on our Spotz2s. :evil:

I certainly hope Spotz is no longer shipping foils with this problem!

:wink: CG

I had a tuttle box that my foil was going a bit too deep into and shimmed it front and back with strips cut from a beer can. Also used to use these for windsurfing fins and works very well.

A good shimming material that tends to be available at most beaches :)
