S-1 PRO _PREMIUM MANOEUVERABILITY
The S-1 Pro 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.
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 materialsThe 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
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 Pro 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.
UNIDIRECTIONAL CARBON FIBRE + OFF AXIS DYNEEMA.
Unidirectional Carbon is aligned to all primary load paths and eliminates any stretch. Off axis Dyneema enables horizontal elasticity, allowing the sail to flex and react with lightning speed. Superior fibres deliver superior performance.
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.
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.
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.
ULTRASONICALLY WELDED SEAMS
Each carbon segment is ultrasonically welded in place. This has multiple advantages over traditional sewing techniques.
PANEL LAYOUT ALIGNED TO LOAD PATHS
Each panel is strategically placed to align with the sails' specific loads, on all sizes.
This has multiple advantages over aesthetic panel layouts
CARBON FUSION
PRECISE. ALIVE. ELECTRIC
Our search for higher performance has brought us CarbonFusion, the next level in load-path sail construction.
Carbon Fusion sails are composed of 3 key componants;
/ MATERIAL
/ FUSED SEAMS
/ LOAD PATH FRAME
The result of these 3 key components effectively turns the sail into a spring. Load it up, and release for explosive performance.
MATERIAL
UNIDIRECTIONAL CARBON FIBRE + OFF AXIS DYNEEMA.
Unidirectional Carbon is aligned to all primary load paths and eliminates any stretch. Off axis Dyneema enables horizontal elasticity, allowing the sail to flex and react with lightning speed. Superior fibres deliver superior performance;
/ DYNAMIC: Carbon warp with no stretch combined with medium stretch 45∞ Dyneema.
/ STRONGER: Dyneema is one of the strongest fibres available.
/ LIGHTER: Carbon has the highest strength to weight ratio.

FUSED SEAMS
ULTRASONICALLY WELDED SEAMS.
Each carbon segment is ultrasonically welded in place. This has multiple advantages over traditional sewing techniques;
/ STRONGER: Full seam adhesion plus the benefit of not puncturing the films with needle holes.
/ LIGHTER: Removal of outer seam tapes and thread.
/ ACCURATE: No seam shrinkage from outer tapes, or thread tension.

LOAD PATH FRAME
PANEL LAYOUT ALIGNED TO LOAD PATHS.
Each panel is strategically placed to align with the sails specific loads, on all sizes.
This has multiple advantages over aesthetic panel layouts;
/ LIGHTER: Aligning fibre accurately with the loads in the sail allows thinner films and much lighter sails.
/ STRONGER: High density of Dyneema and carbon in specific areas.
/ LIGHTNING RESPONSE: Carbon fibre transfers load instantly, without lag due to stretch.
1. PRIMARY LOADS
Primary loads run vertically between head and tack. Downhaul tension transfers directly through the warp oriented carbon.
2. FOOT LOADS.
Foot tensions transfer between the tack and the clew. High density fibreadds impact strength in this area.
3. LEECH LOADS
Leech loads run vertically up the leech, with dynamic loads tensioning the carbon and then springing back for explosive performance.
4. BODY LOADS
Body tension is transferred out of the head and clew.

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.

FAQ
What is the difference between S-1 and S-1 Pro?
The new S-1 Pro is the premium version of the 4 batten S-1 using CarbonFusion technology and high end carbon fibre laminates.
CarbonFusion sails are the only production windsurf sails using carbon fibre laminates from head to tack. Carbon is a higher performance fibre than the Technora, Kevlar, or polyester used in all other sails. Better strength to weight ratios, more reactive, wider wind ranges.
This production technique is highly accurate, reliable, and consistent.
