I am pretty sure there is no issue running a 54 cm Standard tuttle fin in a deep tuttle box ( except for needing bloody long bolts) but just wanted to confirm with the experts out there that it was OK ? Thanks in advance .

Hey Martin, no worries that Ive encountered. I use normal tuttle fins in a Falcon 111 which has a deep tuttle box. Your right about longer bolts but from what Ive seen its the norm.
Only thing is sometimes depending on fin they tend to get pulled "inside" the box.
You can shim them or get an old tuttle fin you no longer want and cut the base down so that you have a block thats sits in the box between the bolt holes and your normal fin "sits" on. Works great and keeps the fin flush with the bottom of board.
Hope this helps as Im no expert.

no problem at all. infact 2 years ago the star board GO was shiped with a deep tuttle box but a normal tuttle fin.

Hi Martin, 54cm is a pretty big fin for a standard base use in a deep tuttle box. Personaly I wouldnt do it for anything over 45cm.
Its must put a lot a strain on the mid section of the box.

I use a 48cm in my formula board - works really well. Makes slalom reaching a pleasure, compared to reaching using the 68cm. As to what it does to the fin box, I cant say... but it hasn't broken... yet...

the starboard hypersonic has a deep tuttle box & ships with a 44cm standard tuttle fin so it cant be too bad..

Tore my favorite fin (Tuttle 41cm Select Superfast) out of it's base on submerged woodwork.
Deep Tuttle box seems undamaged. Question is, do I glue it back so it will never happen again, or is this break out a design feature?

Thanks everybody , My issue isn't so much tuttle in deep tuttle , I know thats cool , it,'s 54 cm tuttle in deep tuttle , is it stretching the freindship ? My research so far suggests maybe yes . *board go tuttle at 52 cm and change to a deeptuttle fin head at 54. Most other brands go deep tuttle fin head around 50 cm . I think it is borderline .

After seeing how a 70 cm fin can be wrecked by a pumping racer ( all the layup starts to protrude ) I should shut up, but surely the change to standard Tuttle fins is more due to the lack of depth in a smaller board for a deep tuttle box? The box itself has lots of strength to spare, you could snap the standard tuttle fin before breaking the box.

I occasionally use really stiff 52cm standard tuttle (have done with several boards). Board seems to do fine, I believe the fin will snap long before damage to the boards. There is a little bit of movement at the base though, deep tuttle definately reduces this.

Oldie, if you glue it back it will eventually break again. The only way to make it last is to dowell the fin.

Thanks, I was starting to consider that solution.
Next time the detached fin might not be so easy to recover.
Will make up a spacer to keep the bases flush while still in a fixing mood..
Some fins have different threads- retapped them all to metric, use same screws for both tuttle and deep tuttle fins.
