2026 Severne S-1 PRO red size 3.3 qm, 1.259,00 €

2026 Severne S-1 PRO

The S-1 Pro is the highest performance 4-batten wave sail. Entirely constructed in CarbonFusion to deliver ultimate reactivity. The carbon fibre instantly transfers power, and welded seams and batten pockets eliminate any lag. Precision.

The S-1 Pro showcases 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 is the ultimate manoeuvre-oriented wave sail.

TECHNOLOGY:

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.
