MS Tûranor PlanetSolar, known under the project name PlanetSolar, is the largest solar-powered boat in the world The vessel was designed by LOMOcean Design, built by Knierim Yachtbau in Kiel, Germany, and launched on 31 March 2010.
In May 2012 it became the first ever solar electric vehicle to circumnavigate the globe.
Technical characteristics 
The 31-meter boat is covered in over 500 square meters of solar panels rated 93 kW,  which in turn connect to one of the two electric motors in each hull. The boat's shape allows it to reach speeds of up to 14 knots. The hull, which is capable of hosting 200 persons, was model tested in wind tunnels and was tank tested to determine its hydrodynamics and aerodynamics. The boat has been designed to be used as a luxury yacht after the record attempt is finished.
The boat is registered in Switzerland and was financed by a German entrepreneur. Construction cost was € 12.5 million. The name Tûranor, derived from J.R.R. Tolkien's novel The Lord of the Rings, translates to "The Power of the Sun".
Around the world 
On 27 September 2010 Tûranor PlanetSolar set off from Monaco to circumnavigate the globe solely with the aid of solar power. One aim of the project was to focus public awareness on the importance of renewable energies for environmental protection.
The boat had a crew of six. Captain of the expedition was Frenchman Patrick Marchesseau. But at the midpoint of the circumnavigation (in New Caledonia in mid-May 2011) the French Canadian Erwann Le Rouzic took over as captain, to share the master's responsibility with Captain Marchesseau. Other participants were Christian Ochsenbein (Bern, Switzerland) and Jens Langwasser (Kiel, Germany); as well as the project initiator, president and expedition leader Raphaël Domjan (Neuchatel, Switzerland).
During the expedition, Tûranor PlanetSolar broke two records: the fastest crossing of the Atlantic Ocean by solar boat and the longest distance ever covered by a solar electric vehicle.
Technical problems with the propeller system forced the vessel to stay in an Asian port for two weeks of maintenance.
Tûranor PlanetSolar returned to Monaco on 4 May 2012 after 584 days sailing around the globe.
The vessel was then scheduled for a refit so it could be chartered to tourists in the Mediterranean Sea. Cruises are planned with 12 passengers and four crew on board.
2013 Voyage and transatlantic record 
After an engine refit, Tûranor PlanetSolar broke its own record, crossing the Atlantic ocean from Las Palmas to Saint Martin in the Carribean in only 22 days, four days faster than on the circumnavigation trip. The boat left Las Palmas on April 25th and arrived in Marigot on Saint Martin on May 18th. The trip will lead to Miami, Florida, and then continue as a scientific expedition along the Gulf Stream.
