DUOTONE WARP_FOIL: EXCELLENT FOIL-RACING SAILING

Posted by antonello on 04 Apr 2023 /

WARP_FOIL expands DUOTONE's range of home sails for PWA and IFCA slalom-fin champions. It is a specific and highly advanced design, aimed at foil racers looking for something that complements the hydrofoil's low fluid dynamic resistance.

Compared to traditional fin navigation, The foil has a lower fluid dynamic resistance of about the 70%. For this reason, a completely different sail design is required. (profile, twist pattern, aspect ratio) to adapt to hydrofoils.

The line 20.23 is completely focused on the new PWA rules for foil slalom. This required a complete redesign from scratch and proved to be the most intensive development of racing sails in the history of the German company..

Development took lead designer Kai Hopf and chief test pilot Marco Lang around the world, between Lake Garda, Southern France, the Netherlands, Tenerife and Maui together with all the athletes of the World Cup team. Fortunately, All these efforts have paid off, since the new WARP_FOIL 20.23 It is simply stunning and surpasses its previous version in the water in all respects.

The new WARP_FOIL 20.23 It will help to fly on the foil not only faster, but also with greater comfort and control. Here's how it was possible to achieve such radical improvements.

WARP_FOIL 20.23 is now characterized by an even higher aspect ratio (Longer luff and shorter boom length) which increases the efficiency on the foil.
The double-layer pocket is now almost doubled, with an extraordinary effect on the aerodynamic profile in flight.
The thrust area has been moved between the hands, so you are always in control, avoiding any instability in an incredible wind range.
One of the most important changes was the replacement of the XPly material in the double sleeve with the PENTA TX. It is an exclusive high-tech material developed 3 years ago by the Kite division. Offers better elasticity than XPly (= more control), but at the same time, has tear resistance 5 times higher and the 50% less deformation than traditional Dacron. In this way it was possible to reduce by almost the 10% weight (400-500g), without sacrificing durability. On the water the difference is even more evident and it has not been possible to find any other racing foil sail that offers such a low dynamic weight!
Another significant improvement is the new FLAT INPUT PROFILE, which reduces aerodynamic drag allowing for higher speed, better acceleration and lift.

According to the German sail factory, WARP_FOIL 20.23 Redefines the benchmark for performance/wind-range ratio: is designed exclusively to win foil regattas!

MAIN FEATURES:

+ DOUBLE LAYER PENTA POCKET TX – increases elasticity and minimizes dynamic weight
+ RADICAL GEOMETRY WITH HIGH ASPECT RATIO – Increases foil efficiency
+ INCREASED POCKET – Huge improvement in the airfoil in flight
+ FLAT ENTRY PROFILE – Reduces drag for higher speed, Better acceleration and lift
+ HYPER CAM 2.0 – Completely new and technically superior: Revolutionary camber with adjustable length, to optimize rotation and increase performance.
