Ultimate Foil – Speed and Slalom
Ultimate 2.4 – The Foil Slalom Sail for Maximum Control and Speed
With the Ultimate 2.4, we introduce the latest generation of our high-performance foil sail. Developed with 20 years of serial sail design experience and 10 years of mast development, combined with valuable feedback from international competitions. The result: a sail that makes no compromises and excels in every racing situation.
Precise Balance, Explosive Acceleration
The Ultimate 2.4 is designed for maximum control and efficiency in foil slalom. The new high-aspect outline ensures optimal handling, while the deeper profile in the boom area generates extra power. A newly designed leech with loose leech starting right at the boom maximizes control across the entire wind range.
Optimizations for 2024:
- High-aspect outline with an extra-short boom for responsive handling.
- Deeper profile in the boom area enables earlier acceleration and consistent top speed.
- New three-piece batten setup stabilizes the pressure point—even in strong gusts.
- Slimmer outline and shorter cross batten allow for quick rotation and clean profile transitions.
- Lighter 2.5 mil X-Ply in the mast sleeve reduces weight and increases profile flexibility.
- Dacron panel optimizes camber rotation and enhances acceleration in gusts.
- Monofilm in the upper sail area reduces weight and delivers a more direct feel.
- Improved leech configuration for more efficient aerodynamics and maximum acceleration.
- Lower pressure point for better control and reduced fatigue during long race days.
The Ultimate 2.4 Foil is the top choice for foilers seeking ultimate speed and performance.

4 Roller cams
Thereof 2 XL-ProCams above and below the boom for stable pressure point and easy rotation.
