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 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.
ALUMINIUM 6063 & 6061
This aluminium alloy boats some very good mechanical properties and can be processed in many different ways while also offering a natural resistance to corrosion.
Produced from an extrusion process, our aluminium profiles make the most of this homogeneous material to provide perfect stiffness both in torsion and bending. All areas in contact with other metals or carbon parts are duly isolated against galvanic reactions.
