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.

Conventional Main Sail - Woven Polyester, Dacron AP

This mainsail is made from a solid woven polyester cloth, often with 2 ply in the leech or the woven dyneema (Hydra net) keeping the nice white look for years and years to come. The cross-cut sail design is a widely used design that is a very price conscious choice. The horizontal full battens help keep the shape, and when lowering the sail, it practically packs itself in to the lazy jack or zippack. The sail is delivered in a sail bag thus easy to store and transport.


The woven polyester used for our KOONAA segment comes in different qualities with high tenacity fibers that resist long term loads. Ranging from an all-round Dacron cloth to high-quality cloth with improved stretch resistance.
