2019 Severne S-1 Sail

S-1

Manoeuvre oriented wave

The 2019 Severne S-1 is a high performance 4 batten wave sail. A reduced batten count makes this sail light, flexible and responsive.

Less structural rigidity gives the rig a bigger sweet-spot, and allows the sail to auto-correct during wave-riding by giving the draft just enough movement to ensure constant power delivery.

Developed on an identical platform as the S-1 Pro, this year’s S-1 replicates the dynamic performance in a more accessible construction.

With it’s 3 or 4 batten interchangeability the S-1 is an extremely versatile wave sail.  The convertible batten system means the S-1 can be run as either a 3 or a 4 batten sail depending on conditions and preference.  The S-1’s very broad range of appeal is matched only by its wind range.

Shaping is located extremely low and forward in the sail, and with a 4th batten added becomes extremely stable. The dropped clew allows short boom lengths for manoeuvrability and boom rigidity.

Built in quality eM3 materials, SpiderFibre, and with a diamond shaped Dacron luff panel for smooth power delivery, this sail is engineered for performance.  Now with eM4 in the lower panels to make the 019 S-1 stronger and lighter.

The S-1 is a manoeuvre oriented wave sail for the modern wave sailor.

KEY FEATURES - 

> SpiderFibre - 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.

> 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 - Durable and lightweight. 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.

> 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.

> Convertible batten system - The 2017 S-1 can be run as either a 3 or a 4 batten sail depending on conditions and preference.

> 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.

> 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 - 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.
