This Foil Aqua Top Plate fits between the mast and the board. This innovative system allows to fix our foil to a board equipped with two US BOX boxes with a center distance of 90 mm.
One side of the Foil Aqua Top Plate holds the aluminum mast profile which penetrates 3 cm and is firmly fixed to the plate with three M6 screws. The connection is perfect in order to avoid any play between the parts, and thus have a precise and reactive feeling.
The holes for the connection to the board are open, so as to facilitate the insertion of the 4 bolts to the nuts inserted in the box of the board. In this way it will not be necessary to unscrew them completely to extract them from the plate.
