Item-no. 14250-1215 · Sizes: 4.6–8.7 · Colors: C18 Black/Violet
The WARP_FOIL extends our PWA and IFCA fin slalom champion sail range. It’s a specific and highly advanced foil design suited for foil racers looking for something that complements the low-drag of the hydrofoil. Compared to traditional fin sailing you have approximately 70% lower drag on the foil. Therefore it requires a totally different sail design (profile, twist pattern, aspect ratio) to match the low-drag hydrofoils.

The design of the 20.24 represented a milestone, as we were able to massively improve the wind range (= improved average speed) and the flight control in the upper range (= improved V-Max). To achieve this we significantly increased the luff curve and reduced the head size. A shortened boom length and the incorporation of a massive double-foil sleeve size were further key design elements.
The WARP_FOIL 2024 concept was very well received, so we decided to build on its success with an evolved version. By updating the batten configuration to a stiffer setup, we’ve maintained the sail's incredible efficiency while enhancing control in stronger winds. This change is paired with a slightly flatter entry of the sail, which improves top speed across all sizes. Together, these updates make the WARP_FOIL an even better foil sail for 2025
In our eyes, the WARP_FOIL 20.25 redefines the benchmark of the control to performance to wind-range ratio. It’s purely designed to win low-drag hydrofoil races.
Attention: for maximum performance the WARP_FOIL is equipped with 4 carbon tube battens. These battens are stiffer but unfortunately also more fragile than glass tube battens. Therefore, they are excluded from our warranty.
Key Features
INCREASED LUFF CURVE
Much increased wind range and more stable flight control in the top end
RADICAL HIGH ASPECT GEOMETRY
Radical high aspect geometry to increases the efficiency on the hydrofoil
MASSIVE DOUBLE FOIL SLEEVE
Tremendous improvement of the flying shape aerodynamics
FLAT ENTRY PROFILE
Reduces the aerodynamic drag to gain more speed, better acceleration plus more lift
HYPER CAM 2.0
Completely new and technically superior: the camber revolution with adjustable length - for optimised rotation and increased performance
Tech Features
Hyper Cam 2.0
Optimum performance and camber rotation at any time. HYPER CAM 2.0 is the camber revolution for even more sail performance.
iROCKET 2.0
Super-lightweight and aerodynamic.
TWIN TRIM CLEW
Wider range of use, custom tuning options. The secret of the TWIN TRIM CLEW is the two horizontally placed clew eyelets.
DURATECH FOOT
Long-term guarantee for the sail foot. When starting off on the water or catching up, the foot of the sail is constantly dragged over the nonslip coating, particularly for wide boards.
HTS 2.0 HARNESSLINE TRIM SYSTEM
Never position your harness lines incorrectly again. Do away with the tedium of adjusting to the optimum rope position, as well as the numb forearms and the endless fiddling around.
MINI BATTEN
These prevent unwanted leech flutter. Short and highly effective mini-battens which provide support for the areas between the battens and prevent undesirable flutter.
VTS - Visual Trim System
Perfect trim and a huge range of use. You won’t find a quicker or more accurate way of trimming your sail.
TT TOP
Improved sail control at higher winds. Designer Kai Hopf originally designed the TT TOP for the WARP.
3D Top Cap
Optimised pull. On regular top caps and pin systems the webbing is connected in a “one-dimensional” way with the sail body (either side to side or front to back), which transfers the downhaul tension only in certain points.
POLYESTER WEBBING ONLY
Eliminating stretch and loss of tension. If it’s good enough for safety harnesses, it’s good enough for windsurfers.

ATTENTION: since the mast geometry and length (= stiffness) depend on the sail design, size and luff curve the sails will NOT work with any masts outside the recommendations.
