Description
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. The secret is a variable slider which gets adjusted via a Torx stainless steel screw, determing the camber length (patent pending). Further extended results in maximum propulsion, slightly shortened optimizes the rotation. The difference is clearly noticeable and has a great influence on the performance level of the sail. The camber length can be changed by anyone within seconds and adjusted to his preferences, even under full sail tension. Despite this unique additional function, the HYPER CAM 2.0 is only slightly heavier since the housing is weight-optimized. But that’s not all that it offers: Advantage 1: Super-fast rigging up (only rolling on instead of snapping on) without having to correct luff and outhaul tension multiple times. Advantage 2: Minimal friction and very gentle batten rotation, since the HYPER CAM has exposed pulleys without plastic braces and only the pulleys touch the mast. Advantage 3: Optimised shape for the best possible luff sleeve profile and ideal aerodynamics. Advantage 4: Suitable for all SDM mast diameters (for any kind of carbon-content or even different brands) because only the pulleys touch the surface and never the plastic structures themselves, allowing the HYPER CAM to rotate with extreme ease. Advantage 5: Fast and easy length adjustment for individual tuning of max. performance vs. ease of rotation. Attention: due to new batten attachment not retrofitable to HYPER CAM 1. generation sails.
iROCKET 2.0: Super-lightweight and aerodynamic. An inconspicuous detail with a massive impact. iROCKET 2.0 batten tensioners are super-lightweight, aerodynamic and highly stable, consisting of high-quality components such as a self-lubricating, salt-water-resistant brass nut with stainless-steel screw which can withstand all batten tensions. Furthermore, the iROCKET 2.0 is an essential component for a true windsurfing revolution. 100% correct batten tension, correctly adjusted when purchased and forever after. We calibrate each individual batten at the factory according to development specifications. And we don’t just leave it up to blind intuition either – all battens are adjusted to 100% accuracy using torque wrenches. We also apply soluble screw adhesive to the locknuts so that the tension cannot be altered. This means that the batten tension remains absolutely correct and will never have to be adjusted again. The batten key included with the sail is therefore only needed for fine tuning or in the unlikely event of a batten breakage.
TWIN TRIM CLEW: Wider range of use, custom tuning options. The secret of the TWIN TRIM CLEW is the two horizontally placed clew eyelets. The outer eyelet position provides more power and a more direct feeling, while the inner position gives more control and a gentler riding feel.
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. With the exclusive DURATECH FOOT, the seams are completely protected within a large plastic channel so that the surface cannot chafe against seams and material.
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. The patented print on the sail shows exactly where the centre of the harness line has to be. All you need to do is position the two ends symmetrically at the left and right of the print.
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. Even beginners can trim the sail in a matter of seconds to 100% accuracy. All you need to do is pull the luff until the top of the loose leech reaches the “lower wind limit” or “upper wind limit”. The VTS acts as a power boost, ensuring maximum performance and broader range of use.
TT TOP: Improved sail control at higher winds. Designer Kai Hopf originally designed the TT TOP for the WARP. The reduced, concave shape improves tension conditions for a more effective, three-dimensional top twist. This means the top twists not only horizontally, but also vertically under strong winds. By completely neutralising gusts of wind, the rig is kept steady in the rider’s hands, and thus works in a much larger range of winds.
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. The 3D TOP CAP allows a “three-dimensional” and very widespread transition of the downhaul forces into the sail body. This eliminates top fluttering and ensures a progressive loose leech extending the wind range. The integrated abrasion ribs eliminate the need for heavy, bulky reinforcements at the end of the luff sleeve.
POLYESTER WEBBING ONLY: Eliminating stretch and loss of tension. If it’s good enough for safety harnesses, it’s good enough for windsurfers! We are the only manufacturer to use only polyester webbing for the (vario) top and the tack roller. This advantage of this compared to conventional polypropylene is the negligible amount of stretch. As a result even brand new sails will retain full luff tension and will not need subsequent trimming.
