When I hit the bottom my front feet always flew out of the strap before the board hit the water.
The force of rotation moment of the board on the mast broke (happend twice) on the front of the tuttle box not on the front strap.
is hard not to be ironic here, but we know that all types of vehicles that required low weight and high resistance structure use carbon over aluminium. You dont suspect why?
We can discuss if the aluminium is more cost efective for some free ride foils, but not if is more resistance.
How is the process to shape hi grade Aluminium?
a 3 axis CNC router I think. And you need a big block to shape a anedral wing. Probably one wing cost half of a mold that you need to make a hi precision carbon wing.
