Description
The most radical foil racing sail
The Warp_Foil 20.26 is Duotone's foil racing sail. With a foil there is roughly 70% less drag than with a fin, and that calls for a different approach to profile, twist and aspect ratio. Building on the 20.24 (more luff curve, smaller head, shorter boom and double foil sleeve), for 2026 it debuts a new luff sleeve construction: less movement up top, more stability, less drag and better acceleration. It's made to order.
Sizes 4.6 – 7.5 m² · 7 battens · With cams · SDM mast
Who it's for
- Windsurf foil racers.
- Foil riders looking for maximum average and top speed.
What makes it special
01 More luff curve
Much more wind range and more stable flight at the top end.
02 Radical high-aspect geometry
More efficiency on the foil.
03 Double foil sleeve
A huge improvement in aerodynamics in flight.
04 Flat entry profile
Less aerodynamic drag: more speed, better acceleration and more lift.
05 Hyper Cam 2.0
Cams with length adjustable by a screw: better rotation and more performance.
Where it shines: foil racing (slalom and course racing) across the whole wind range.

Data from Duotone's official chart. Boom and luff are the maximum measurements for each size. Vario top: adjustable, takes more than one mast length; Fixed: not adjustable. Mast: recommended / alternative model and diameter (RDM or SDM); recommended / alternative length. If you're unsure between two sizes, choose the smaller one if you're light or ride in strong wind, and the bigger one if you want to plane earlier. Check the selector for the sizes available in store.
“The best thing about the Warp_Foil, what sets it apart from any other racing sail, is that it comes race-ready straight out of the bag.”
Technology and construction
- New 2026 luff sleeve: more stability, less drag and better acceleration.
- Seven battens and 4 cams + 2 Sleeve Inducers: a stable profile at top speed.
- Four tubular carbon battens: stiffer but more fragile: Duotone excludes them from the warranty.
- Twin Trim Clew: two clew eyelets for more power or more control.
Which one to choose?
- Warp_Foil 20.24: the previous version, if you can find your size.
- F_Pace Cam: foil performance in a more accessible package.
Pair it with: a Platinum Series SLS SDM mast, a Platinum SLS boom and a Power.XT 2.0 extension.
Frequently asked questions
Which mast do I need?+
The one the chart gives for your size: type (PLATINUM, GOLD…), diameter (RDM or SDM) and length. Duotone warns that the sail only performs well with the recommended masts, because stiffness depends on the design and the size.
What does MTO mean?+
Made to order: ask us about lead times and availability.
Are the carbon battens covered by the warranty?+
No: Duotone warns that the four tubular carbon battens are stiffer but more fragile and excludes them from the warranty.
