SEVERNE S-1 2025

The S-1 redefines what a 4-batten wave sail can do, delivering unparalleled lightness, flexibility, and responsiveness. Designed for all wave conditions, this powerhouse sail excels whether you’re carving tight turns, launching aerial moves, or pushing vertical maneuvers.

Lightweight Power, Precision Performance
With a reduced batten count, the S-1 is lighter and more agile than ever, offering more back-hand pressure compared to the Blade. This calibration lets you explode into vertical turns or dominate in aerial transitions with precision and control. A fat head design on the latest generation S-1 opens dynamically under load, expanding the performance envelope with enhanced high-end control and a broader wind range. For smaller sizes, the refined aspect ratio reduces twitchiness, creating a balanced and intuitive feel.

Next-Generation Construction
The 025 S-1 incorporates cutting-edge XFusion technology, where ultrasonically welded foot panels replace traditional stitching. This innovation delivers a lighter, more responsive sail without weak points caused by stitching wear. Borrowing from the PRO series’ CarbonFusion technology, XFusion makes premium performance accessible to more riders.

Both the S-1 and S-1 Pro are developed on the same platform, with the S-1 Pro offering an unmatched experience through its advanced CarbonFusion construction, while the standard S-1 brings the same dynamic performance in a more accessible build.

Advanced Materials for Peak Durability
The S-1 is crafted using premium materials, including VX2, SpiderFibre, and eM4, ensuring unmatched strength, reduced weight, and controlled stretch. The proprietary Gradient Panel Technology enhances power transmission, durability, and longevity, giving you the confidence to push your limits in any conditions.

Built for the Waves
Engineered for maneuverability, the S-1 thrives in waves of all sizes—from playful knee-high swells to towering surf. This sail delivers the performance you need to excel, whether you’re honing your style or competing at the highest level.

Experience the ultimate balance of power, control, and innovation with the S-1—your ticket to peak wave-sailing performance.
