The Warp_Foil 20.26 represents the latest evolution of Duotone’s dedicated racing foil sail. Hydrofoils generate up to 70% less drag compared to traditional fins, which requires a completely different sail design. That’s why every detail – from profile and twist to aspect ratio – has been re-engineered to perfectly match the low-drag characteristics of foiling.
A key milestone in this development was increasing the luff curve and reducing the head size. This results in improved high-end stability and enhanced flight control. Shortened boom length, a massive double foil sleeve, and a stiffer batten configuration with a flatter entry further boost acceleration, extend top-end speed, and provide better handling in gusty winds.
For 2026, the Warp_Foil introduces a new mast sleeve construction. The result: reduced sail movement, lower aerodynamic drag, and faster acceleration. These refinements set a new benchmark in the balance between control, performance, and wind range – making the Warp_Foil 20.26 purely designed to win foil racing events.
Note: The sail is equipped with 4 carbon tube battens. These battens are extremely stiff and performance-oriented but more fragile compared to glass battens. They are therefore excluded from warranty coverage.
Product highlights
WIDE WIND RANGE
Increased luff curve ensures better flight control and higher top speed
STABILITY IN STRONG WINDS
Stiffer battens and flatter entry improve control in gusts and high wind conditions
NEW MAST SLEEVE CONSTRUCTION
Less sail movement, lower drag, and better acceleration
PERFECTLY FOIL-DEDICATED DESIGN
High aspect geometry, massive foil sleeve, and optimized twist for maximum efficiency on the foil
Features
- Increased luff curve - extends the usable wind range. The sail remains stable in stronger winds while maintaining early flight in lighter conditions
- High aspect geometry - improves aerodynamic efficiency and maximizes the potential of the low-drag foil, delivering more speed with less physical effort
- Double oversized foil sleeve - stabilizes airflow and improves the flying shape of the sail, generating more low-end drive and smoother acceleration
- Flat entry profile - reduces aerodynamic drag, increases acceleration and lift, and helps maintain a steady flight at high speeds
- Hyper Cam 2.0 - the latest generation of camber inducers with adjustable length. Provides smoother rotation during tacks and gybes and allows fine-tuning for different conditions and riding styles
