Boost 2026

Ultimate Freewave

The Boost 2026 continues to deliver the ultimate combination of power, control, and versatility in the freewave segment. Whether you’re blasting through bump & jump conditions, carving powerful turns in onshore waves, or pushing into big loops, the Boost provides the drive and stability you need with smooth and balanced handling.
 
For 2026 the innovative Continuous Radial Panel Layout brings a new level of refinement to the Boost. By aligning sail panels along natural load paths, this innovation distributes forces more efficiently than ever before, reducing seam stress and enhancing profile stability. The Boost now feels more direct and responsive, with smoother power delivery and lasting performance across a wide range of conditions.
 
A powerful and controllable five batten construction defines the Boost, stabilized by Carbon Radial Tapes spreading from the clew to maintain a locked-in profile. The result is a sail that feels strong and reliable, yet reactive enough to handle dynamic maneuvers and changing conditions with ease.
 
The Boost’s freewave DNA makes it the perfect choice for riders who want one sail to cover it all – from onshore waves to blasting in chop. Combined with the Continuous Radial Panel Layout, the 2026 Boost delivers an unmatched blend of stability, drive, and responsiveness, making it the go-to option for ambitious freewave sailors.

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 – CONTINUOUS RADIAL PANEL LAYOUT
We’ve revolutionized the panel layout by creating continuous panels that run radially from the sail’s center. By eliminating cross seams, which are common in traditional horizontal and vertical panel setups, the whole panel works as a unit with a better feedback to the loads.

2 – 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.

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.

NEW IN 2026 : THE CONTINUOUS RADIAL PANEL LAYOUT.

This season we also introduce the revolutionary Continuous Radial Panel Layout on Manic, Manic HD and Boost models.

This innovative design uses continuous panels aligned with the sail’s natural load paths, eliminating cross seams for better load distribution, enhanced stability and improved responsiveness.

The result ? Sails that offer smoother handling, greater efficiency and top-end performance across all parameters.
