The S-1 Pro is the highest performance 4-batten wave sail. Next Generation materials raise the performance levels even higher. For 027, SEVERNE pushes forward with three new technologies;
PROJECT85: the introduction of Project85 in the main leech area reduces the physical weight by 25% but makes even more difference to the swing weight.
CLEAR CARBON: A clear version of SEVERNE’s CarbonX-Ply adds extra vision to the sail and increases strength. Used in the clew and foot areas.
TAFFETA X-PLY: Adds a smooth feel and balanced power delivery, whilst still being able to be welded to the body panels.
The S-1 Pro is the pinnacle of SEVERNE’s construction technology: the complete sail including the batten pockets are welded CarbonFusion. This creates a smooth, stitchless sail from the back of the mast sleeve to the leech. Eliminating the thousands of micro-holes created by the stitching has multiple benefits:
/ INSTANT RESPONSE; LESS STRETCH AND MOVEMENT UNDER LOAD
/ STRONGER
/ SMOOTHER
The S-1 Pro leads the way with a balance of technology and sail design.
The S-1 Pro is the ultimate manoeuvre-oriented wave sail.
/ 4 BATTEN DESIGN
/ CARBONFUSION WITH MONO WINDOW
/ DEVELOPED WITH JAEGER STONE
SIZES: 3.6 / 4.0 / 4.4 / 4.6 / 4.8 / 5.0 / 5.2 / 5.6
TECHNOLOGY
The S-1 Pro is built entirely in welded CarbonFusion from the back of the sleeve to the leech, batten pockets included. No stitching means no micro-holes; less stretch and movement under load.
For 027 three new materials join that platform: Project85 in the leech, which cuts physical weight by 25% and swing weight with it; ClearCarbon in the clew and foot; Taffeta X-Ply in the luff. A PRO-specific panel layout keeps seam length to a minimum; less weight, more reactivity. Here's the full rundown.
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.
PROJECT85
Project85 is the new leech panel material for 027. In the leech area it cuts physical weight by 25%.
The bigger effect is on swing weight. With less mass out at the leech, the sail feels faster, lighter and more immediate in the hands.
Project85 is used on the 027 Blade Pro and S-1 Pro.
/ 25% LESS PHYSICAL WEIGHT IN THE LEECH AREA
/ REDUCED SWING WEIGHT
/ FASTER, LIGHTER, MORE IMMEDIATE IN THE HANDS
TAFFETA X-PLY
Taffeta X-Ply is the new luff panel laminate for 027. Its base is a plain-woven fabric with tightly twisted yarns, which give it a crisp, slightly stiff hand.
In the luff panel that translates to a smooth feel and balanced power delivery. The laminate is fully weldable to the CarbonFusion body panels, so there is no stitching where the luff meets the body.
Taffeta X-Ply is used on the 027 S-1 Pro and Blade Pro.
/ PLAIN-WOVEN BASE, TIGHTLY TWISTED YARNS
/ SMOOTH FEEL, BALANCED POWER DELIVERY
