Severne Blade Windsurfing sail 5.7m 2023

Severne BLADE Windsurfing sale 2023, bought by a customer 6 months ago and never used.

CONTROL ORIENTED WAVE

The Blade has defined the 5-batten wave sail category for nearly two decades.

With the new Gradient Panel Technology, improvements are apparent. Lighter weight and better stability. 

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 stretched over time. It's a more stable way of building sails. 

Rather than a single curved luff panel, the Blade 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. Total control.

TECHNOLOGY - 

VX2
> Material - VX2 is a vertically oriented X_Ply featuring increasedfibre density for stability and control, reduced film thickness for less weight, and out proven scrim layer for dependable durability. The 2 signifies the film thickness in mil. 
> Advantages - VX2 laminate significantly reduces deformation in the sail compared to eM3 material. The vertical stretch has been reduced by more than 20% whilst the horizontal stretch characteristics have increased fractionally to enhance the elastic springy feel that has deifned the SV wave sails. 
> More stable. More durable. Less weight. 

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, 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. 

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.  

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.

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

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 - Protevts your board from impact and neatly covers the foot detailing. It incorporates the rope stash pocket for easy storage of your downhaul rope. 

3&4 ROLLER TACK PULLEY - roller tack pulleys are matched to the sails downhail requirements and aligned for friction free downhauling and threading ease.
