SolarRig Sàrl is a Swiss cleantech company that develops, builds and tests rigid solar wing sails for catamarans and yachts, enabling low‑emission and ultimately zero‑emission propulsion for shipping. Its founder Mark Wüst was part of the first solar‑powered Atlantic crossing with the catamaran sun21 in 2006/07 – a world record of about 7,000 nautical miles without a drop of fuel – and has been building solar‑powered boats for more than 30 years.
