The main innovation is based on the very low drag of the whole made possible thanks to the thinnest fuselage of the market coupled with the FRDS system, technology developed and patented by AlpineFoil. This technology allows both a high level of rigidity and an exceptional flow.
The carbon elements are combined with an aluminum fuselage because this material allows a reduction of the fuselage section of 40% compared to a carbon section while offering an excellent reliability thanks to its strong resistance.
The foil is also ultra thin and light, while being particularly rigid: a considerable work of reduction of weight was carried out according to the Material Resistance to arrive at a ratio stiffness / thinness out of the common run.
The carbon / aluminum union and this extreme thinness make the A1 Carbon a unique windfoil on the market.

The AlpineFoil carbon mast, a must-have:
The main asset of windfoil A1 Carbon is its full carbon RTeam mast. The choice to offer a mast in true carbon fiber continues to demonstrate the desire of AlpineFoil to transmit extraordinary sensations to its customers. To achieve superior rigidity, the carbon fiber layers are laid out in a precise orientation that meets all our flexion and torsion requirements and is then fired at very high pressure, ensuring ultra-compact carbon and therefore unequaled strength and resistance.
So that this supreme rigidity does not affect the quality of the glide, AlpineFoil has designed a mast whose profile is progressive. Each area of the mast has been carefully studied according to the constraints, there is strictly no superfluous. Thus, the upper part of the mast is thicker, because it represents a significant area of stress concentration, while the lower part is much thinner, to greatly reduce drag and thus optimize the glide to the maximum. The rigidity is so impeccable while the glide remains absolutely sensational.
The size of this 100% windfoil mast is also extremely important. Results of a laborious calculation, the 95 cm of length are perfect for navigation at sea. An excellent upwind, a very good amplitude of maneuver, progressive takeoff and piloting: this mast greatly facilitates the practice of windfoil in marine environment. Added to this is a primary advantage: a perfect balance between stability and responsiveness. Indeed, a mast too short would be unstable because the lever exerted on the sail would have been too weak, while a longer mast would be too much nervous and therefore much more difficult to handle. Here, the research conducted has generated a product that responds perfectly to the slightest solicitation of the pilot.
Then, the mast rope was also evaluated at the fairest. Its size is not too wide, to avoid the saffron effect that makes the foil difficult to handle and increases the drag, not too fine, to maintain a certain stability. These precise dimensions greatly contribute to improving the upwind ascent, but also, combined with a suitable profile, to optimize the rigidity in flexion and torsion of the mast to 100%.
the leading edge is well marked while the trailing edge is extremely fine. This AlpineFoil system allows excellent flow, and therefore a great reduction of the drag, which gives you an unparalleled level of glide.
This high-end mast then benefits from an ultra-refined finishing process. Instead of just sanding at the exit of the mold, AlpineFoil, with a taste for excellence, prefers to push the finishing to its climax.
The masts with gloss option, unlike the matte versions, have an additional treatment. This high performance finish on the one hand refines the design of the product, and on the other hand greatly improves its glide.
The mast is equipped with a very special Deep Tuttle box: it is integrated into the mast. Being completely molded with the mast, the carbon fiber is uninterrupted, from the base of the mast to the top of the housing, which guarantees a housing of exceptional quality. This MCBox technology (Monobloc Carbon Box), developed and patented by AlpineFoil, significantly increases the rigidity of the mast / housing connection. In addition, it involves several other strong points:
- A very small bulk,
- Ultra fast assembly,
- A big reduction of the drag.
The Deep Tuttle format also has a major advantage: it is a standard that fits on many boards. AlpineFoil has chosen to provide two optional recovery plates: one to place under the hull of the board, the base of the box, the second on the deck, each serving to further increase the distribution of efforts. The objective is to stiffen the whole and to limit the risk of damage of the box of the board by spreading the constraints on the entire of it.
The ULW 900, the ideal wing for windfoil.
The wing ULW 900 will be the wing delivered by default with your foil. If all the AlpineFoil wings are usable in windfoil, the ULW 900, with its surface of 943 cm², remains the pinnacle for this practice.
- An excellent lift / drag performance, for optimal glide in Light Wind,
- A much worked profile, to eliminate the problem of lift when the speed increases and for extraordinary gliding sensations,
- A curved wing, for an extraordinary stability, because the curve locks the vectors of lift in a single point,
- A progressive curvature calculated to remain perfectly constant in turns,
- The VAS technology (Variable Angle System), which allows a very wide speed range,
- A fixation system by AlpineFoil with four screws in staggered rows, to completely remove the pivot and to increase the rigidity and stability of the whole.
Like the mast, the wing is made of 100% carbon fiber.
Its profile is inspired by the Race wing, which gives it an optimal glide and stability.
The fuselage, a perfect balance between thinness and rigidity.
It is an aluminium fuselage machined in the mass, because this process allows to take advantage of all the properties of the material. The ratio between rigidity and thinness is optimal. The result is an ultra-rigid and ultra-thin product that provides an ultimate glide feel, as well as an outstanding lightness.
