Duotone Warp_Foil - completely redesigned featuring an increased luff curve and reduced head geometry for improved flight control and wind range. 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. 

Duotone increased the luff curve which leads to a much more controlled and balanced behaviour when fully powered up. Increased luff length even further allowed to reduce the head geometry. The smaller head creates a smaller leverage thus improves control and balance again.

The boom length got shortened, which reduces the backhand pressure. Increased sail twist between batten 1-3 for more release which improves top speed and acceleration. The massive double-foil sleeve is now made out of 4 pieces and has a tremendous effect on the flying shape aerodynamics.

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 Duotone warranty!
