The Surf-Foil appeared in the 2000s. Among the precursors, there are great names like Laird Hamilton, Dave Kalama or Paolo Rista. Originally, it was just a way to fly over the water in surf-traction, in large swells. In 2016, it was Kai Lenny who blew away the number of practitioners. The discipline immediately conquered Hawaiian, Australian, Californian and Brazilian surfers. The level is skyrocketing. Progressively, foil surfing is arriving in Europe, and in France. The advantages of the Foil are to multiply the number of possible sessions, of practicable spots, and to offer new sensations. We will explain in this article the functioning of a surf foil with its different parts and we will detail the importance of the characteristics of the front wing.
Composition of a Surfing Foil
The Foil is composed of the following elements: mast, fuselage, front wing and rear wing (stabilizer).
The front wing has a curved upper surface and a flatter lower surface. The front wing has a rounded leading edge that quickly increases in thickness, then tapers to a thinner trailing edge. The chord is the width of the front wing (from the center of the leading edge to the center of the trailing edge) and the span is the length (the right/left end) of the wing.
Finally, the stabilizer has a shape quite similar to the front wing, with equivalent properties. However, it has a reduced surface and a different profile.
