A direct descendant of the Mach race sail program, the NCX blends the design concepts that maximise speed, power, and stability with the user-friendliness of a no-cam sail.XR (Xtended Range) was developed to increase wind-range at both the lower AND higher ends: deeper, more powerful profiles are locked in place with added skin tension to enhance control and stability.Open leech. Twist patterns are taken directly from the latest World-Cup designs. Geometry. Longer boom lengths deliver more backhand pressure for acceleration on demand.Race construction – graded monofilm for stability and max performance. Multiple tube battens.
