RIG ERGONOMICS: A unique focus for SEVERNE Sails is rig ergonomics. By analysing the overall effect the sails geometry has on the sailor, we are able to build sails that are more comfortable to use in a larger range of conditions. Technically, this is achieved through analysing the following points:

• Placement of the centre of effort in the rig
• Rake angles, pitch, and sheeting angles
• The application of the sail and the specific characteristics required for each sail range

Once these elements are analysed and adjusted, we can deliver the most comfortable stance possible for each sail design.

SEVERNE focus on developing a larger “sweet spot” or area of sailing trim where the rig performs more efficiently. This translates into rigs that are significantly more predictable and that allow the sailor to easily respond to changing wind and water conditions.

DESIGN PHILOSOPHY: SEVERNE develops sail that are lighter, faster, easier to rig and tune and meets design goals based on function.

SEVERNE has developed a much more responsive set of sails that retain their control over a wide spectrum of use. Dropping into a bottom turn or initiating a high speed gybe; power is instantaneous and smooth. Drive is locked low and forward in the sail, giving a predictable, balanced feel throughout its wind range. These are purist sails, designed with performance and handling capabilities that extend their ease of use.

SEVERNE sails are built using 3 specific zones, designing materials to suit the demands in each area of the sail.

CONTROL ZONE: The upper section of the sail defines the control characteristics of the sail. This is done through varying the parameters such as twist and skin tension. To reduce the overall weight and swing weight of our sails, the most technically advanced, lightweight materials are used in the upper section. Reducing film thickness and running rig loads through multiple fibres reduces the weight of our sails significantly and promotes light handling and a throw around feel.


POWER ZONE: The mid section generates the sail’s power; the mechanical stability of this area is paramount. Materials used in the luff panel will dictate how the pressure is disbursed into the sail. Wider spaced X-ply materials and intelligent panel layouts maximise vision whilst maintaining durability. This is important in all models, especially wave sails, to enable critical timing on the wave.


IMPACT ZONE: Heavy duty materials are kept lower in the sail, an area traditionally prone to damage. Thicker films, twisted fibres and stronger yarns are used to increase the durability in this area and keep the extra weight low in the sail.




SHAPING TECHNIQUES: For a much more consistent foil shape when the mast is being loaded and unloaded in extreme conditions, we engineer the 3D position of each point on the entire foil to the sub-millimetre. We then join the seams with a complex web of internal and external reinforcements for solid seam construction. This process translates into wider wind ranges and a more balanced, consistent feel at all times.

SPEED & RESPONSE: Superior handling, an active feel and balance allow you to utilise the rig as your on-demand power source. We build these foils for performance; engineering them light so they respond immediately to wind, water and rider input. An instant decision can be executed without the sail dynamics taking time to catch up. Traditionally a priority with racing sails, the idea of speed is critical in the design of our freeride sails. We have tuned each model for maximum speed, without losing focus on any of the important freeride factors.

DURABILITY THROUGH DESIGN: We demand the strongest sails, but we will not compromise on weight. Rather than use the traditional approach of just beefing up high load, high stress areas with heavy materials, we have concentrated on balancing the skin tensions by using high tech materials such as Aramid and Technora for reinforcing. An example of this is the Aramid Torsion Frame, used on selected high end models where the perimeter is reinforced with Kevlar. This can be seen inside the boom opening where these materials are visible. Vulnerable stitching is protected with recessed grooving used within the moulded soft edge and the batten abrasion protector on larger sails where the sail is likely to touch the boom. We also use innovative, folded patch technique in the foot areas.

STYLING: In our quest to bring you the ultimate product, we bring balance, innovation and a progressive design ideology in our sails. Function is always balanced by refinement and attention to detail, from our biggest race sail to our smallest component.
