The Helix continues to lead the revolutionary Sigma Series. For 2009, it has been totally redesigned to provide super fast turning, superior glide, great upwind ability, easier water relaunch, more direct bar feel, and a 5th line friendly option. These improvements have been achieved by reducing the number of struts, lowering the aspect ratio, developing a new bridle platform and reworking the arc; making it the first ever GeoTech generated C-shaped arc. We have also incorporated the Low Drag Wingtip and Direct Response Steering technologies into our new wingtip design. To complete the Helix line, we have added two new sizes. For intermediate to advanced riders who seek the highest all-terrain performance, and those looking to course race."
