KA makes the sail design software used by the leading brands...
We are the leading provider of windsurf sail design software with most of the leading sail brands using our technology to design their sails. So...quite possibly, you already have a sail created using KA know-how! (We don't usually mention who uses it, but we figure a quote from the north-windsurfing front page can't get us into trouble: "Besides his legendary fin designs, Kai’s sail design programs are used to update the McSail design software, which is used by all sail designers of all major sail brands nowadays. This software allows a much more accurate and faster development of new sail profiles and generates the important data for mass production.")

KA makes sails that perform for real people...
Professional sailors know what they want in a sail when it comes to high performance. But this is not the whole story... Our expertise has always been in translating this requirement into designs that make real people feel like pro's.

KA sails are incredible value...
We don't have a big marketing budget, we choose to let our sails speak for themselves. What you will find is that KA are much better value than the others. Same materials, same construction, better design at a great price to you.

Our Mission...
Stay in the lead as designers of high quality, high performance sails. We want our customers to have as much fun as we are. We will never make a sail that you won't like and we will back that all the way.
