The carbon mast was designed to combine maximum rigidity with minimum drag. In 100% carbon, it has a Deep Tuttle box at the masthead. We’ve added a flange too, to strengthen the box and relieve stress on the hull. Beneath the fuselage, a conical box with three screws reinforces the connection between mast and fuselage. The mast contains no foam, to ensure minimum flex and twist along with maximum reliability.
