The outline and width of each boom are optimized for either the Wave, X-Over, or Race sail range to help with a more ergonomic and efficient stance. All features ensure that your sail is turbocharged and performing to maximum design potential. Drive your sail with maximum responsiveness, with instant feedback, at the flick of a wrist. A unique combination of design, materials, and technology.
