BLADE PRO_PREMIUM CONTROL
The BladePro takes the Blade concept to the next level. Built entirely in CarbonFusion to make it lighter, more responsive and more stable than standard construction. This is Philip Köster’s sail.
New for 026, even the batten pockets are engineered using CarbonFusion. This creates a smooth, stitchless sail from the back of the mast sleeve to the leech. Eliminating thousands of micro-holes created by stitching delivers multiple benefits:
/ Instant response – less stretch and movement under load
/ Stronger – no stitch line failure points
/ Lighter – significant weight reduction through welded construction
The BladePro is the ultimate control-oriented wave sail for any conditions.
/ 5 BATTEN DESIGN
/ NEW 3.1 AND 3.4 SIZING ON SMALLEST SAILS
/ CARBONFUSION BATTEN POCKETS
/ DEVELOPED WITH SCOTT MCKERCHER AND PHILIP KÖSTER
SIZES 3.1 / 3.4 / 3.7 / 4.0 / 4.2 / 4.5 / 4.7 / 5.0 / 5.3 / 5.7 / 6.2 / 6.7

TECHNOLOGY
The SEVERNE BladePro and S-1 Pro are built entirely in welded CarbonFusion from sleeve to leech – no stitching means no failure points and significant weight reduction.




GRADIENT PANEL TECHNOLOGY
The Blade Pro uses 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.
Rather than a single curved luff panel, the Blade Pro 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.


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 components;
/ 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.


XTENDED RANGE
Xtended Range technology that allows for bigger gaps in your quiver.
Xtended Range was developed to increase wind range at both the lower AND higher ends: deeper, more powerful profiles are locked in place with added skin tension to enhance control and stability.

Fat Head
The fat head design - adapted from S-1 development — opens further under load, improving high-end control without compromising stability. Smaller sizes feature proportionally larger heads for maneuverability, while larger sizes balance head size for aerodynamic efficiency.


CAMO 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.
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.

What changed from 025 to 026 Blade Pro?
The 026 Blade Pro now features CarbonFusion construction across the entire body, including the batten pockets; a first for this sail. Combined with DirectConnect technology that locks every connection point, this creates a sail that reacts instantly with zero lag.
What is the difference between the Blade and the Blade Pro?
The key difference between the Blade and Blade Pro is the material, as well as, the construction.
Blade Pro is the only sail that is built using carbon fibre laminates from head to tack. Carbon is a higher-performance fibre than the Technora, Kevlar, or polyester used in all other sails.
Better strength-to-weight ratios, more reactive, wider wind ranges.
The Blade Pro features Carbon Fusion
The Blade Pro uses carbon fibre laminate from head to tack
The Blade Pro is more reactive
The Blade Pro features a better strenght to weight ratios
What is DirectConnect technology?
DirectConnect locks every connection point to create a structural spring that delivers immediate response with zero energy loss. Traditional designs allow flex where components meet, creating power lag – DirectConnect eliminates this for instant reaction to rider input.
Can I rig the Blade Pro on a SDM mast?
No, the Blade Pro is designed for RDM masts.
WHAT IS THE DIFFERENCE BETWEEN THE BLADE/BLADE PRO AND S-1?
The S-1 is a manouvrable oriented sail, meaning it has more backhand drive, allowing you to effortlessly change lines during your turns, wave 360, or aerial setup.
The Blade is kept neutral in the front of the sail to give a lot more control when riding or jumping.
The S-1 has 4 battens.
The S-1 is more manoeuvre oriented.
The S-1 has more backhand pressure.
The BLADE has 5 battens
The BLADE is more control oriented.
The BLADE is more stable.
The BLADE is full X-PLY
WHAT IS THE DIFFERENCE BETWEEN THE BLADE/BLADE PRO AND GATOR?
The Blade/Blade Pro is wave orientated whereas the Gator is a freewave/freeride oriented crossover sail.
The Blade/Blade Pro is specifically designed for the windsurfers who spend most of their time in the waves. A neutral sail that helps to improve riding and jumping.
The Gator will be your best match if you enjoy bump and jump conditions, occasionally riding some waves. Offering a softer, easier handling, the Gator will have you planning earlier than anyone else.
The Gator is freewave/freeride oriented.
The Gator planes earlier.
The Gator has five battens up to 7.0 and six battens from 7.5 and up.
The Blade is more wave oriented.
The Blade is more stable.
The Blade is more manoeuvreable.
The Blade is less freemove/freeride oriented
IS IT POSSIBLE TO GET CARBONFUSION AND OTHER REPAIR MATERIALS?

HOW DO I RIG MY BLADE/BLADE PRO?
Check out our rigging guides section: https://www.severnesails.com/product-care/rigging-guides/
Can I rig the Blade Pro on a non-Severne mast?
All of our development, testing, rigging, and tuning are done using SEVERNE masts.
We strongly recommend our customers use SEVERNE masts. Our masts are designed with a specific SEVERNE bend curve that remains one of the pillars of our rigs.
We don’t test the performance or bend curves of other masts, and can thus not guarantee which performance or durability you can get out of your sail using a different brand mast.
We describe the curve of our mast as a SEVERNE curve.
The constant, hardtop, or flex top curves that generic mast brands describe base themselves on measurements on 3 points.
We measure our masts at 7 points minimum.
