Different layouts

  • X-CUT
  • EPEX
  • X-CUT
    A cross-cut sail (x-cut) consists of a number of horizontal panels parallel to each other and perpendicular to the leech. This is a very cost-effective way of producing a sail, making it affordable and long-lasting. Being the first sail-design on the market, the x-cut sail has a long and proven track-record.
    Cross-cut sails are typically made from a woven polyester cloth with straight fill yarns that are stronger than the warp yarns. The strong fill yarns are aligned with the load bearing direction of the sail resulting in a very durable sail.
    Trioptimal layout is also referred to as radial, since the panels are radial typically oriented towards the corners of the sail resulting in a triangular shape. This layout distributes the forces the sail is exposed to optimally and helps maintain the shape of the sail. The panels that make up the radial layout are carefully arranged to follow the load pattern, ensuring a strong and stable sail.
    Upwind sails in a trioptimal layout are typically made from a laminate cloth, that is a sandwich cloth constructed of more layers. However, you will find a few trioptimal designs in a woven polyester cloth, and most nylon downwind sails are designed in a trioptimal cut.
  • EPEX
    The unique and patented EPEX membrane technology is the flagship of Elvstrøm Sails. A 100 % custom design where every single yarn is placed according to a load path design, computer calculated to the individual sailing preference. This enables the absolute optimal distribution of fibers over the entire sail resulting in an outstanding shape stability and performance.
    A broad range of materials and fibers are available to meet every need. The components are bonded under extreme and constant vacuum that evacuates all air, holds the membrane in place, and compresses the membrane components.

Fathead - Double Taffeta, Vectran/Technora

The EPEX layout, with optimum fiber distribution allows us to build a stable and efficient Square Top. An optimum designed square head provides easy trimming and control. When the wind increases, the top of the sail will twist, and the result is a flatter sail. In light wind the extra area gives the boat more power. The square head mainsail has full battens, which in addition to making the sail stable when sailing also makes the sail pack itself when lowering it in to your zippack. The double taffeta layer protects the sail from chafe, wear and tear and additionally it protects the fibers from UV degrading. We will together with you find the best solution regarding type of fibers and surface combinations.


Taffeta is available in light and heavy and in grey and white. The Vectran/Technora fiber combination is the most popular fiber combination for the cruising sailor both high performing and durable.
