New for 2016, the GT Speed is the our top-of-the-line Freeride wing. The GT wing is a 100% Race Team (RT) product, meaning that it is manufactured exclusively by its designer and his closest collaborators in Alpinefoil HQ at the foot of the French Alps.

The GT wing is designed for riders who already have some solid foiling experience and are looking for increased speed, maneuverability, and airtime. With a pronounced wing curvature, and a moderate wing area, the GT is stable and easy to ride even at the highest speeds. MCF construction makes the foil super stiff and super light,  making it the ideal wing for foil riders who like to get big air, and the Variable Angle foil System (VAS), and the ultramodern wing shape will provide fast smooth carving sessions regardless of the water conditions. 

AlpineFoil Kitefoil wing technologies: 

MCF (Monobloc Continuous Carbon Fiber)

Now present in all our carbon products, MCF construction provides an exceptionally high strength and rigidity. With MCF we mate the two halves of the wing with filament winding, thus eliminating the traditional glue joint. We get a seal without any weak point, with an elongation factor of 1.6 to 1.9% compared to about 40% elongation for a glue joint.

AlpineFoil mounting system

The 4 mounting holes are staggered to best support the connection of the wing to the fuselage, ensuring the rigidity and cohesion of the whole system. Screw heads are countersunk to fit snugly in the wing, reducing friction and improving glide. This system now standard on all Alpinefoil wings and allows full compatibility with all our existing and future foils, including Alpinefoil 4.0, Alpinefoil 4.5, Alpinefoil 5.0 Full Carbon, Alpinefoil Access 5.0, and Access 5.0 Alpinefoil V2. 

"Arrow" swept wing shape

All of our foil wings are designed with a swept wing angle, more or less pronounced depending on the type of wing. This swept wing design is extremely important for stability. These complex shapes require 30% more carbon fiber in the manufacturing of our wings compared to a right-angle wing.

Dihedral curvature

The dihedral curvature of all our wings is designed and developed in a digital wind tunnel. This curvature is one of the most important parameters in the design of a kitefoil wing. The principle is simple: a curved wing will have bearing vectors that intersect at a point, radically improving the stability compared to that of a flat wing where none of the vectors intersect. The dihedral curvature also greatly affects the lift and stability of the wing. A curved wing reduces parasitic roll, stabilizing the wing's trajectory and thus increases steering precision. The curvature also helps to maintain lift and reduce the tendency of a foil to "hunt". 

VAS (Variable Angle foil System)

All Alpinefoil wings are designed with a dynamic load profile between the center of the wing and the wing tip. This unique Alpinefoil feature uses a high lift wing tip providing the lift you need at low speed, resulting in better control and extraordinary stability. With an increase in speed (and thus a decrease in incidence), this effect gradually fades to decrease the wing load and refocus the lift, allowing the wing to achieve higher speeds while remaining extremely stable. This results in greater speed range and a very progressive stall.
