S-1 PRO _PREMIUM MANOEUVERABILITY
The new S-1 Pro is the premium version of the 4 batten S-1.
These 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. There are no differences in finished sail weights.
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.
The boom length has been shortened on bigger sizes (4.8 and up) to reduce the back-hand pressure that builds up as the wind increases. Instead, the power has been shifted up in the sail giving more leverage to accelerate instantly in light winds.

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
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.
