There are many fastening systems to connect the foil to the board, each brand of kitefoil has chosen or created a box for various technical or commercial reasons. We offer a short summary of the current solutions with their advantages and disadvantages.

Tuttle Box

This box has been used by many brands of kitefoil from the beginning because it was already much used in windsurfing as well as in race for kitesurfing. The box inserted into the board was therefore easy to find and especially inexpensive.

The box shown in this picture is a standard tuttle, note that it exists the same in deep tuttle version, which is longer. It is mostly used for windsurfing or very thick boards to provide better anchorage.

This box format is nevertheless one of the hardest to push connect of these non-beveled edges. It needs a lot of force on the foil to insert it in the board, this is not ideal, especially if the board rests on a hard surface like a parking.

The advantage of this model is the low height of the case (in its standard version) which allows it to be installed on boards with little volume.

The KF Box is the first box developed 100% for foil, this format was drawn by the brand Ketos. It represents a good evolution compared to the tuttle box because it has beveled edges which allows it to be inserted more easily while maintaining a good anchorage in the board.

We regret however the rectangular and non-pyramidal structure like the box Pro Box which would have made it even easier to install. Like the tuttle box, the KF Box is not very high which also allows him to connect on boards not very thick.

It is for this reason that brands like Fone have chosen this box for their foil.

The Pro Box is the latest design, also developed for the foil. It is the Taaroa brand that used this format for the first time, not surprising since it was designed by Select Hydrofoil, the manufacturer of Taaroa foils.

This box is without a doubt the easiest to install and remove thanks to its pyramid shape. It fits into the board without any effort and requires only a slight lever to remove it.

The Sroka brand has also chosen this box format for these foils. However, this box is criticized for being a little too high, which limits its use on thin boards.

Would a mini box pro box be the ideal solution?

The plate fixing system is one of the strongest since the various forces exerted by the foil on the board are distributed over the whole of the plate. This system offers a surface that is more important than any box, it is therefore much more resistant.

Nevertheless some foils are molded directly with the plate on the mast like especially the sword 1 which increases the thickness of the mat and considerably complicates the transport in boards bag. Unless the board is integrated via an adapter as in the picture.

This last solution offers the possibility of making its foil compatible with more boards. Zeeko and Ketos offer a lot of compatibility thanks to this system.

Sliding rail

The board brand Camet has developed a universal fastening system since it allows to connect any mast of foil. The principle consists of 2 rails for fasteners and a main rail for inserting an adapter type tuttle, Kf box or even pro box.

This fixing system is slightly more fragile than a box molded directly in the board but unless hitting an obstacle at high speed, no problems have been reported.

Note also that the rails can slide, so it will be possible to adjust the position of the mast under the board. This position could varies depending to the foil used since the power generated by the wings can varies.

It is therefore an ideal system to have a board compatible with all models if you have also possess all adapters.
