Boost 2025

Ultimate Freewave

Introducing the Boost: The ultimate blend of control, durability and power in a 5-batten setup! Catch waves, boost into huge jumps and experience the thrill of windsurfing like never before.
 
The Boost windsurf sail has been meticulously designed using state-of-the-art 3D software to provide windsurfers with an unparalleled experience on the water, whether you’re heading for a radical wave or exciting freewave session.
 
Compared to the Manic, the Boost sail comprises a slightly longer luff and boom, making it a more powerful and performance-oriented option. It’s ideally suited for onshore conditions, strong winds, jumping and excels both in waves and flat water chop.
 
If you’re a windsurfer looking to take your skills to the next level and crave a sail that offers unmatched performance and versatility, the Boost is your ticket to an exhilarating and dynamic windsurfing experience.

Quality, advanced technology and innovation means everything to us.

Our goal is to provide every surfer with the perfect sail for his or her demands, which is why we implement the right materials and features for each application area.

Depending on the sail model we use the suitable combination of different materials of highest quality to achieve the perfect mix of lightness, durability, power and handling.

Quality, advanced technology and innovation means everything to us and each step in the development process is extensively planned to offer unique windsurfing performance.

FEATURES :

1 – 2-PLY CONTINUOUS LUFF PANELS
The Boost sail incorporates two continuous luff panels made from our exclusive 2-Ply material. This unique construction not only enhances the sail’s strength but also ensures more efficient load distribution, resulting in a sail that reacts directly to your commands.

2 – INTEGRATED BATTEN TECHNOLOGY
All the battens above the boom feature our Integrated Batten Technology for maximum symmetry and stability. This design choice optimizes the sail’s performance across a wide range of conditions.

3 – 5-BATTEN SETUP
To further enhance stability and performance, all sizes of the Boost sail are equipped with a 5-batten skeleton. This configuration provides the perfect balance between power and control.

4 – LIGHTWEIGHT CONSTRUCTION
The Boost is constructed to be lightweight, with the top half of the sail crafted entirely from our ultra-durable 2-Ply material (1.75 mil in the center and 2.5 mil at the leech). This construction reduces weight without compromising strength.

5 – CARBON RADIAL TAPES
The sail’s profile is stabilized by carbon radial tapes spreading from the clew, ensuring that the sail maintains its shape and responsiveness even in demanding conditions.

6 – ENHANCED STABILITY
We’ve reimagined the sail’s outline to improve stability and reduce backhand pressure. This means you’ll have better control in a huge range of conditions, allowing you to push your limits with confidence.

7 – ONE-PIECE MAST SLEEVE
The one-piece mast sleeve makes the Boost lighter and improves stretch characteristics.
