Koonaa 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.
Material
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.

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. -
