We don't use trim box anymore, what do you mean by euro? I gather by mast track you mean standard US box (like a mal has?)

I'm guessing you are building a kite race board and want to carry big fins/

Theoretically due to load dispersal-

Deep Tuttle > Conic > Tuttle > Trim > Power > US

As Mark said Trim (& Conic) don't really exist any more.

That said I've hit a reef which with a well built US box sunk into block of hd foam and it sheared fin in half, the same hit would have broken most tuttle boxes and broken the fin head on power box.

thanks for the feedback. The US is probably the only that will be applicable for what we are doing.Can you fit 10mm screws in the Us Box?

^^^ why would you wish to?

Are you talking about where the bolt comes down thru the board form the deck? (Powerbox or Tuttle)?
A US box has a very small bolt

All been done before with hydrofoils, and kiters think they are first so now they want to make them for windsurfers?

Intheloop??? comments? I'm insanely curious....

But if you wnat to make a hydrofoil fin the load is enormous so deep tuttle would be the go.
And keep it clean to maximize the interference fit
