Development of a prototype motorsailer: Autark-Zero. A completely self-sufficient and emission-free yacht of 12m, equipped with electric propulsion and a carbon wing-sail.

The retractable wing-sail serves 3 purposes: sail, solar harvester and cockpit roof. The wingsail has a A-symmetrical airfoil for maximum lift-coefficient; trailing edge flaps can trim the wingsail to optimal
camber. Covered in PVcells potentially harvesting 5kW.
Control is completely automated; all moving parts are electrically powered: wing-sail, mast, dagger
boards, rudders and engines, everything being controlled centrally by the autopilot system, enabling
automated and even autonomous tactical sailing. The innovative design has been patented.
