Severne S1 2023

Description

S-1

MANOEUVRE ORIENTED WAVE

The new S-1 is built on the exact same pattern as the S-1 Pro but uses VX2 and eM3 laminate materials to reduce cost with only 150g added weight. (depending on size).

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 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 shifter up in the sail giving more leverage to accelerate instantly in light winds.

Upgrades to 2023:

> Gradient Panel Technology
> More stable
> Less stretch
> Lighter

 

TECHNOLOGY

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.

EM4 HIGH LOAD LAMINATE

> Based on the proven eM3 platform, the high load eM4 material features twice the amount of X-Ply fibre and increased film thickness to maximise durability. This new material allows weight reduction whilst maintaining puncture resistance and tear strength. Used in the lower impact zone in the sail.
– Scrim: Polyester
– X_Ply : Polyester x2
– GSM : 190GSM

SPIDERFIBRE

> A fibreglass filament with very high tensile strength. Used to mimimise weight and maximise strength. Traditional sail-making utilises small corner patches that diffuse the load approx 30cm, often ending before or even at a seam creating a weak spot.
Severne use a web of SpiderFibre that transfers the load out of critical areas to diffuse throughout the body of the sail. By using stronger, lighter fibres these radials measurably reduce weight and increase strength. Lighter, stronger sails.

DOUBLE SEAMS – All Severne wave sails have 25mm double stitched window seams. The wider, single colour seam tape ensures maximum tear strength and crash resistance.

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.

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.

SEAMLESS FOOT CONSTRUCTION – A single panel in the foot area with hidden load patches and zero exposed stitching eliminates seam abrasion and seam creep in this high load area. Maximum durability and minimum weight.

3&4 ROLLER TACK PULLEY – Roller tack pulleys are matched to the sails downhaul requirements and aligned for friction free downhauling and threading ease.

 

In comparison:

S-1 Pro – S1 is less expensive

Blade – S1 has 4 battens and is more manoeuvre oriented. The S1 has more backhand pressure.

Blade Pro – S1 has 4 battens, more manoeuvre oriented and more back hand pressure.
