Control Oriented Wave

The 2019 Severne Blade is a 5 batten wave sail with the perfect blend of power and control. For riders demanding dependable performance across a wide wind range you simply can’t beat the stability and control that 5 battens provide. Based on this fundamental Severne built the Blade to be the ultimate all-rounder wave sail.

Product Description

Increased luff curve adds skin tension to hold the profile forward and low to maximise wind range. A Dacron luff panel allows elastic expansion under load, furthering the draft-forward bias when conditions get extreme. The control oriented geometry sets the rake angles to maintain downforce at the mast base whilst setting the clew below shoulder height where it can be most easily managed. Stance is balanced with the upper shaping moved forward to put less pressure on the back leg and reduce fin load.

Constructed entirely out of premium X-Ply, the Blade is one of the most durable sails on the market, yet intelligent design means it’s also one of the lightest. SpiderFibre technology has radically reduced swing weight whilst also creating a much stronger clew. Dyneema window X-Ply allows for unrestricted vision. Upper panels in eM3 reduce swing weight. The new highly durable yet lightweight eM4 material is used in the high load foot area. Double width seams lock every panel in place. Engineered for performance.

The 2019 Severne Blade is the sail to choose for all-round high performance.

Key Features

  • 100% Xply
  • Double seams everywhere
  • Benchmark wave sail

Upgrades for 2019

  • Increased stability and control
  • Cyclops-ready



Seamless Head Panel

This high abrasion area is made from only 1 panel and does not carry any exposed seams, preventing any potential weak point in this area. As a result, seam creep and seam-related failure have been eliminated.


eM3 is developed to combine the performance of the e-series cloths with maximum durability. The addition of a 90-degree pre preg polyester scrim has provided unique tear resistant characteristics and the off-axis loads are carried through the 22-degree X-ply fibres. The red and new blue adhesive maintain the UV resistance and tear strength, while the reduced film thickness significantly reduces the weight. The use in the upper panels reduces not only the overall sail weight, but also the swing weight, aiding manoeuvrability and control. Used in the BLADE and in the FREEK.

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

Boom Height Reference

Boom height gauge for ease of reference.


A web of fibreglass filament that disburses loads across seams and throughout the body of the sail. By using stronger, lighter fibres and reducing sail patching, we can measurably reduce weight and swing weigh and at the same time, increase strength.


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.

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.

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.

3&4 Roller Tack Pulley

Roller tack pulleys are matched to the sails downhaul requirements and aligned for friction free downhauling and threading ease. Rig your sails with the Severne Hardware Division extensions for function and simplicity.

    The best just got better!
    Im super impressed how Severne improve a already excellent wave sail.
    The 2019 Blades feel slightly lighter in the hands and pull slightly further forward than previous years,making them really stable and focused.They accelerate quickly and smoothly and as they have five battens make a great high wind blasting choice!Top end on these sails is fast.
    On the wave the 2019’s feel really manouverable and composed,quick directional changes are not a problem.
    The X-Ply looks like it can take a battering and the Build quality is first class.
    The best got better,

    I love my new 5.0m Blade. The first time I took it out I reckon that I sailed better than ever before, because the sail was making manoeuvres so much easier. Light and smooth, yet very stable and composed. Massively strong build quality.

  3. Tom Saunderson

    First time out with my new 5.7m Blade yesterday. Incredibly light in the hands and sits beautifully on the 400cm Blue Line. Matched with a carbon boom, the rig is incredibly light and responsive and seems to get the board planning in noticeably less wind than on my previous similar sized sails.
