Speed sailors need little introduction to the Koncept. As the sail which hold the all time fastest average speed on GPSSS and has reached a 2 second peak speed in excess of 50 knots, it is held in the highest regard. What is not so widely known is how accessible the Koncept is to all sailors who crave speed. With 7 battens, 3 cams and a moderate width luff sleeve, the Koncept is a really friendly sail , easy to rig, light and manageable on the water. This is definitely not a beast designed for pro racers only. For 2010 every detail has again been put under the microscope. The outline has been changed with some area removed from the head and added in the boom area. This has increased top speed by reducing drag and also improved the low end power and acceleration. The clew “cutaway” has been increased for a lighter feel and improved leech twist, and the luff sleeve has been widened in the boom area for even greater draft stability. Durability has taken another step forward with a whole range of abrasion resistance features added. Simply put the Koncept conquers!! Sizes for 2010 are 5.3, 4.9, 5.7, 6.4, 7.3, 8.3
