I bought a new board last year. None of the info available describes the fin box, but when I asked the distributor I was advised in writing it was tuttle. The board doesn't come with a production fin, so I ordered two new tuttle fins for it. When it arrived, I was surprised to find it's actually fitted with a deep tuttle. It's only a 91L slalom. I now have the problem of the fins deeply recessing into the board. So far I've tried tape and then spray putty on the front and back of the fin, but I had to apply so much to get the fit that the putty is cracking and chipping off under pressure - wont last more than a few goes.

I've already had some fantastic advice from Isaac and Keef, but just thought I'd check if anyone has any magic solutions to fit tuttle fins to a deep tuttle box?

I understand there's a couple of brands that put deep tuttle boxes in small boards. What are the advantages of doing this?

Any hot tips greatly appreciated!
