ENIGMA – For ultimate performance


In a traditional x-ply sail, very few of the fibres are aligned with the load of the sail, this means the film takes the load, this means the film has to be thicker and heavier.

In a HyperSpider sail each membrane is custom built for each sail size and model. Every fibre is aligned along its exact load paths, this mean film thickness can be reduced making a lighter sail.


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.

Aero batten pockets

In the quest to create a truly symmetrical sail, Severne have developed the Aero Batten Pocket. Rather than add the batten pocket on one side of the sail, the panels of the sail are overlapped to create a channel for the batten. The tensioner is then loaded from both sides of the sail creating even tension across both sides of the foil.

The result is improved sail symmetry, and reduced weight.
