Forskellige layouts

  • X-CUT
  • TRIOPT
  • EPEX
  • X-CUT
    Et crosscut (x-cut) sejl består af et antal horisontale parallelle paneler i lodret linje mod agterliget. Det er en effektiv og økonomisk måde at producere holdbare sejl på. Som det første sejldesign på markedet har det bevist sit værd. Crosscut sejl fremstilles typisk af vævet polyester dug med lige skudtråde, der er stærkere end kædetrådene. De stærke skudtråde ligger i belastningsretningen af sejlet og giver dermed et meget holdbart sejl.
  • TRIOPT
    Det trioptimale layout går også under navnet radial, da panelerne er radiale mod hjørnerne af sejlet, der giver den triangulære facon. Sejldesignet gør, at belastningen på sejlet fordeles mere effektivt og dermed holder sejlet bedre sin form. Panelerne i det radiale layout er nøje placeret i forhold til belastningen for at opnå den bedste stabilitet. Medvindssejl i trioptimal layout er typisk lavet af et laminat, der er en sandwich dug bestående af flere lag. Men det trioptimale layout anvendes også til modvindssejl, der typisk fremstilles af nylon.
  • EPEX
    EPEX er vores unikke og patenterede membran teknologi, vores flagskib. Et 100 % custom- design, hvor hver enkelt tråd lægges ud nøjagtigt i forhold til designet af hver enkelt sejl. Det giver den helt optimale fordeling af belastningen på sejlet, der får en enestående form-stabilitet og ydeevne. En bredspektret udvalg af tråde giver et utal af kombinationsmuligheder, der møder ethvert behov. Materialerne i en EPEX membran presses sammen under ekstrem og ensartet vakuum og efterfølgende laminering.

Fathead - GPR Black, Carbon/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.

Material

GPR Black is an all-black film/film membrane, very light and racing oriented. The Carbon / Technora fiber combination is an optimal solution in terms of shape and performance.

 

Performance - Durability - Price

Performance, durability and price indicators are illustrated for each material combination on a scale from 1-10, 10 being the highest.

 

Other Mainsails

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

  • Conventional Main - short battens
  • Conventional Main - full battens
  • In-Mast Furling Main - no battens
  • In-Mast Furling Main - short battens
  • EMS Main
  • EMS Max Main
  • EMS FatFurl Main
  • In-Boom Furling Main
  • Conventional Main - short battens

    Conventional Main - short battens

    Sail Type
    The conventional mainsail with short battens still has full top batten. Having shorter battens in the lower parts of the sail makes the trimming and depowering easier. Short battens also make the sail weigh less and is normally the preferred choice for racing. Short battens also mean less chafe against the rig and spreaders when sailing downwind, so it should be considered if you plan to cross the oceans and sail downwind for long distances.

    The sail can be delivered with slides or luff rope, reefs and all other necessary options, for instance: trim stripes, sail numbers, cunningham, over-head leech line, loose foot and sail bag.

    Layout
    Available in cross-cut, trioptimal and EPEX.

    When to use
    The conventional mainsail with short battens can be used in all weather conditions – upwind and downwind. For heavy wind conditions the sail area can be reduced by reefing.
  • Conventional Main - full battens

    Conventional Main - full battens

    Sail Type
    The horizontal full battens in the conventional mainsail help keep the shape of the sail, and when lowering the sail, it practically packs itself into the lazy jack or zippack. As the sail is easy to use and stable, it is a favorite sail for many cruisers.

    The sail can be delivered with slides or luff rope, reefs and all other necessary options, for instance: trim stripes, sail numbers, cunningham, over-head leech line, loose foot and sail bag.

  • In-Mast Furling Main - no battens

    In-Mast Furling Main - no battens

    Sail Type
    This is the simplest in mast furling mainsail. Cost effective and solid are the most important features. It is possible to furl into all furling masts, also the ones with a narrow opening.

    Normal options to include are clew block, clew UV cover, reefing marks and sail bag. Sail number, trim stripes and other options are also available.

  • In-Mast Furling Main - short battens

    In-Mast Furling Main - short battens

    Sail Type
    This in-mast furling mainsail with short battens can be built with a straight leech which gives a larger and more efficient sail than without the battens.

    Normally this sail will also fit into all masts, also the ones with narrow opening, as the battens are flat. It is a cost effective and solid sail. Normal options to include are clew block, clew UV cover, reefing marks and sail bag. Sail number, trim stripes and other options are also available.

  • EMS Main

    EMS Main

    Sail Type
    The EMS is an in-mast furling mainsail with full continuous vertical battens. The continuous vertical battens with carbon top provide support for the leech, whether the sail is fully deployed or reefed. The battens are also to be used as reefing points, stretching the reefed luff and making the sail flat and efficient.

    Normal options to include are clew block, clew UV cover, reefing marks and sail bag. Sail number, trim stripes and other options are also available.

    Sail Type
    The EMS max sail is the cruising in mast furling mainsail that also win races. The sail area can be designed as a conventional mainsail, but with several extra features.

    The continuous vertical battens with carbon top provide optimal support for the leech, whether the sail is fully deployed or reefed. The short intermediate battens have the same function. The full battens are also to be used as reefing points, stretching the reefed luff and making the sail flat and efficient.

    Normal options to include are clew block, clew UV cover, reefing marks and sail bag. Sail number, trim stripes and other options are also available.
