The extended mast of a pro box adapter fits under the board. The whole thing is perfectly rigid and fixed. The more rigid the foil assembly, the better its performance.
The board is very accessible thanks to its volume and a hull particularly designed for foil. The inverted rails make it easy to wind up so you don’t get stopped every time you hit the chop.
Equipped with straps with several possible positions, you can adjust the balance of the foil by changing the position of the straps further forward or further back.
