Different layouts

  • X-CUT
  • TRIOPT
  • 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.
  • TRIOPT
    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.

Code C - Laminate

The Cruising Code is all about comfort, easy handling and generating power. You hoist the Code while it is furled around the cable it is connected to. You unfurl the sail and instantly you power the boat up and make it go. We make the geometry in a way, so you can prepare and hoist the sail in the harbor before you head out. When you finish using the sail, you furl it away and return to your mooring and take the sail down. You will be able to use the sail in angles between 70° TWA to 150° TWA depending of the wind speed.

 

 

Other Downwindsails

If the above product example is not what you are looking for, check out all the other downwind sails in our KOONAA, Multihull segment.

  • Light Spinnaker
  • Heavy Spinnaker
  • Gennaker
  • Furlstrøm
  • Furlstrøm XL
  • Asym spi 2A
  • Asym spi 3A
  • Asym spi 4A
  • Asym spi 5A
  • Light Spinnaker

    Light Spinnaker

    The light Cruising Spinnaker is an all-round spinnaker with less leech and foot roach, to make the sail more stable (easy sailing).

    Can be used at angles from 120-170° TWA. Perfect together with our Spisock ( Snuffer) for easy and safe handling.

    TWA: 120-170°
    TWS: 4-24 kn
  • Heavy Spinnaker

    Heavy Spinnaker

    The heavy Cruising Spinnaker is like the light spinnaker. Can however be used in more wind.

    Can be used at angles from 115-175° TWA. Perfect together with our Spisock (Snuffer) for easy and safe handling.

    TWA: 115-175°
    TWS: 15-32 kn
  • Gennaker

    Gennaker

    The Cruising Gennaker is close to the A2 but with less roach in luff and leech, to make the sail more stable (easy sailing).

    Can be used at angles from 130-165° TWA. Perfect together with our Spisock (Snuffer) for easy and safe handling.

    TWA: 130-165°
    TWS: 4-24 kn
  • Furlstrøm

    Furlstrøm

    Furlstrøm is probably the most easy to handle downwind sail you will ever find. The hoisting, unfurling and furling is made extremely easy due to the built in cabling in the luff.

    The sail was made to add some power to the boat when sailing at angles when the jib is no longer helping the performance much. You would use it in lighter conditions at angles from 70° TWA. With medium breeze you can sail as deep as 140° TWA with the sail.

    TWA: 70-140°
    TWS: 5-25 kn
  • Furlstrøm XL

    Furlstrøm XL

    The Furlstrøm XL is a Gennaker that furl s around a loose anti-torsion cable. It furls from the top and down.

    It can be used at the same angles as the cruising gennaker 130-165° TWA. It has a smaller head angle for better furling.

    TWA: 130-165°
    TWS: 10-24 kn
  • Asym spi 2A

    Asym spi 2A

    The A2 is your full size running gennaker. It has max girths and a large head-angle. It is the largest and most powerful sail in your inventory.

    It is still made of a light material which gives the sail a wide range for its use. TWA from 130- 165° at 10/11 –20 knots TWS. The geometry and design of this sail will allow you to sail close to the same angles as you would with a symmetric sail.

    Size factor: 100%

    TWA: 130-165°
    TWS: 10-20 kn
  • Asym spi 3A

    Asym spi 3A

    The A3 is your reaching sail. It is a sail made in stronger material. It is intended for angles between 100-135° TWA when the pressure is up between 10-18 TWS. The size of the sail is greatly reduced from the A2 to allow the sail to be sheeted on for the tight angles without having return in the mainsail.

    One can argue that the A3 would be a possible alternative to the Code 0 in cases, where you do not want to take the hit on the rating using a Code 0.

    Size factor: 85% of A2.

    TWA: 100-135°
    TWS: 10-18 kn
  • Asym spi 4A

    Asym spi 4A

    The A4 is your “full size” heavy weather runner. It is intended for use on the angles you are seeing, when you are sending your boat on a breezy downwind leg.

    You will typically see angles between 140-165° TWA and wind speeds from 17-26 when on this sail.

    Size factor: 96% of A2.

    TWA: 140-165°
    TWS: 10-18 kn
  • Asym spi 5A

    Asym spi 5A

    The A5 is your fractional sail. It is for use in gale force winds. It will give you more freedom in steering your boat in steep waves and it will keep the bow nicely out of the water because of the fractional halyard position.

    Your heaviest and smallest gennaker in your inventory. Because of the reduced size you can get to higher angles with this sail than with the full size sail. You will be able to use it from 125-160° TWA at 15-30 TWS.

    Size factor: 70 % of A2

    TWA: 125-160°
    TWS: 15-30 kn
