Product Description

Rigging A 2017 Severne Blade Windsurf Sail

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. New Dyneema window X-Ply allows for improved vision. Upper panels in eM3 reduce swing weight, and heavy duty heX-Ply in the foot for impact strength.

The 2017 Severne Blade is the sail to choose for all-round high performance.

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.

Thermoformed head patch

Protects the adjustment webbing and head assembly stitching from wear during rigging, carrying and launching.

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.

Internal printed x-ply

Printing the films prior to lamination with the x-ply gives us the flexibility to use multi-coloured, custom graphics. The print is of minimal thickness, reducing weight and producing a higher definition of colour. During lamination the printed side is placed on the inside of the film so there is no need to worry about wear. Your sails will forever remain looking bright and fresh.

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. Rig your sails with the Severne Hardware Division extensions for function and simplicity.

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.

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.

    This is my new benchmark in windsurfing sails. You really should demo one and see for yourself. See the blog for my full review.
