S-1 PRO

PREMIUM MANOEUVRABILITY

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.

CARBON FUSION TECHNOLOGY

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 - 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.

The result of these 3 key components effectively turns the sail into a spring. Load it up, and release for explosive performance.
