S-1Â _MANOEUVRE ORIENTED WAVE
The S-1 is the high performance 4 batten wave sail. The reduced batten count makes this sail light, flexible and responsive. Engineered for any type of conditions, this lightweight powerhouse redefines responsiveness. The S-1 has more back-hand pressure than the Blade, calibrated to go vertical or launch into aerial moves.
A fat head on the latest generation S-1 opens more under load to increase the performance envelope; more high-end control and wind range. The aspect ratio has been decreased on the smaller sizes to reduce twitchiness. Combined with the fatter head, the area distribution is more obvious.
The 025 S-1 utilises XFusion technology; ultrasonically welding the foot panels, negating the need for stitching. Lighter, more responsive, and no stitching to wear out. XFusion is an evolution of CarbonFusion technology used in the PRO sails that have trickled down to more accessible models.
Both the S-1 and S-1 Pro are developed on an identical platform. The PRO construction offers the ultimate experience while the S-1 replicates the dynamic performance in a more accessible construction.
Proprietary GRADIENT PANEL TECHNOLOGY reduces weight, increases strength, and controls stretch logically. Direct transmission of power. Increased longevity.
The S-1 is built using premium materials. The S-1 features quality materials including VX2, SpiderFibre, and eM4. The S-1 Pro is crafted in CARBON FUSION.
The S-1 is a manoeuvre-oriented wave sail to excel in waves from knee high to as big as they go.

TECHNOLOGY
VX2
VERTICAL XPLY 2.0MIL./ MATERIAL VX2 is a vertically oriented X-Ply featuring increased fibre density for stability and control, reduced film thickness for less weight, and our proven scrim layer for dependable durability. The 2 signifies the film thickness in mil./ ADVANTAGES. VX2 laminate significantly reduces deformation in the sail compared to eM3 material. The vertical stretch has been reduced by more than 20% whilst the horizontal stretch characteristics have increased fractionally to enhance the elastic springy feel that has defined the SV wave sails.MORE STABLE. MORE DURABLE. LESS WEIGHT.
SPIDERFIBRE
A web of fibreglass filament that disburses loads across seams and throughout the body of the sail. By using stronger, lighter fibres and reducing sail patching, we can measurably reduce weight and swing weigh and at the same time, increase strength.
GRADIENT PANEL TECHNOLOGY
The GRADIENT PANEL TECHNOLOGY logically reduces weight, increases strength and controls stretch. Overall weight is reduced but the more significant improvement is the feel – quicker reacting and lighter feel.Rather than a single curved luff panel, the S-1 uses separate panels that radiate out of the head and tack corners. This perfectly aligns the sail material with the direction of load. Previously the curved panel would have bias stretch in all the wrong places. Direct transmission of power. Increased longevity.
EM4 HIGH LOAD LAMINATE
Based on the proven eM3 platform, the high load eM4 material features twice the amount of X-Ply fibre and increased film thickness to maximise durability. This new material allows weight reduction whilst maintaining puncture resistance and tear strength. Used in the lower impact zone in the sail.
MOLDED SOFT EDGE
With recessed grooving, covering any vulnerable stitching the moulded soft edge encloses the hard edge long the foot of the sail and protects the stitching from wear along the board non-skid.
THERMOFORMED TACK FAIRING
Protects your board from impact and neatly covers the foot detailing. It incorporates the rope stash pocket for easy storage of your downhaul rope.
3&4 ROLLER TACK PULLEY
Roller tack pulleys are matched to the sails downhaul requirements and aligned for friction free downhauling and threading ease. Rig your sails with the Severne Hardware Division extensions for function and simplicity.
GRADIENT PANEL TECHNOLOGY
With the new GRADIENT PANEL TECHNOLOGY improvements are obvious. Lighter weight and better stability.
Using the new GRADIENT PANEL TECHNOLOGY. Corners have overlapped panels which reduces the amount of patching. At the same time these overlapped areas extend into the body of the sail so it transitions the load much better, will be less stretch over time. It’s a more stable way of building sails.
The GRADIENT PANEL TECHNOLOGY logically reduces weight, increases strength and controls stretch. Overall weight is reduced but the more significant improvement is the feel – quicker reacting and lighter feel.
Rather than a single curved luff panel, we use separate panels – split luff – that radiate out of the head and tack corners. This perfectly aligns the sail material with the direction of load.
Previously the curved panel would have bias stretch in all the wrong places. Direct transmission of power. Increased longevity.

2026 Severne Blade Windsurfing Sail – CC2
BLADEÂ _CONTROL ORIENTED WAVE
More power. All the control. The Blade delivers 5-batten stability without the traditional weight compromise. Forward driving profiles and reduced backhand pressure mean slight wind variations go unnoticed. The sail does the work; you focus on sailing. The 026 Blade has been rebuilt from the ground up to increase power and integrate the latest development concepts: XR Xtended Range: Developed to increase wind range at both the lower AND higher ends. Deeper, more powerful profiles are locked in place with added skin tension to enhance control and stability. Fat Head: Originally developed for the S-1, the increased head roach opens further under load, improving high-end control and wind range. Smaller sizes have relatively fatter heads whilst bigger sizes balance the head size for better aero efficiency. DirectConnect: A system of directly connecting the load points of the sail to any hardware – masts, battens and boom. Zero lag means the sail reacts instantly to rider input. CarbonFusion Trickle-Down: The BladePro construction is trickling down into the Blade, with welded foot panels and carbon load transfer strips in the head and tack. Gradient Panel Technology: Overlapped corners logically reduce weight, increase strength and control stretch. The 026 Blade sets a new standard by integrating these design concepts with industry-leading materials, including VX2, SpiderFibre, eM4 as well as the new D6 Dacron in the luff. The Blade is the control-oriented wave sail for any conditions.
2025 Severne Hyper 8 Foil Race Windfoil Sail – 9m ONLY
HYPER CHARGED FLIGHT.
The Hyper’s legacy is undeniable; countless national, continental, and world titles over the years have established it as the definitive benchmark in foil racing. The next generation Hyper 8 introduces design enhancements that notably elevate performance metrics that matter. A more open and narrower head design not only increases outright speeds but also ensures a smoother power transfer. Flat entry profiles shift the deepest point further back, resulting in enhanced glide and a slippery in-flight sensation. This low-drag configuration is essential for maintaining stability across a wide range of winds; this is essential for optimal board trim. A rigid batten frame eliminates unnecessary movement when winds intensify and the rig powers up. Increased stability equals more speed. The intuitive feel of the Hyper 8 adapts to a broader wind range, enhanced by the Xtended Range design. Keep pushing for longer, stay focused on the race, not your equipment. Don’t be fooled though, the Hyper 8 responds to input with decisive precision. Fly First Class. / HYPER 8 UPGRADES / More open head for comfortable/smoother ride and more top end speed. / New, stiffer battens. / Smaller head on specific sizes. / 9.0 has gained wider range, better handling / Less physical – push for longer SIZES  4.0 / 5.0 / 6.0 / 7.0 / 8.0 / 9.0
