The F-ONE aluminium mast can be fitted with a number of options to connect with the board. Choose from a 4-bolt top plate, a standard Tuttle head, a KF or a DKF head.

All versions are fastened to the mast through a sleeve and a two-bolt system. The Mast Top parts are machined out of solid blocks of 6061 aluminium. The accuracy of the CNC makes sure the geometry of the connection is perfect. Stainless steel inserts are used systematically to preserve the durability of the fastening connections. The Top Plate has become a market standard and is compatible with any board featuring a twin track system. The bolt spacing we use is 160×90 mm but our latest version also features an option for 165×90 mm.

The Top Tuttle makes F-ONE foils compatible with all Tuttle boards. The Tuttle format is the original and standard format. A flange has been added around the base of the head to better spread the load through the structure of the board. The KF and DKF heads make current F-ONE foils compatible with kite or SUP foilboards produced previously with these boxes.
