The 12.5 million euro Tūranor PlanetSolar, entered the record books as the first electric boat to complete a (585 day) world circumnavigation. She arrived at the Hercule Harbour in Monaco on Friday the 4th of May at 2:15p.m. Celebrations to welcome the crew back to Europe were arranged after they crossed the finish line.

Raphaėl Domjan, the project founder, is set to reveal that highlights of the eco adventure. There will be a party to include a “SolarLightShow” and a music concert featuring the Swiss band Sonalp, all to be powered by solar energy stored in the boat’s batteries.


The MS Tūranor PlanetSolar will have sailed almost 60’000 km across every ocean powered only by energy from nature. The whole crew, including the engineers, organisers and sponsors deserve the biggest accolade for daring to dream the impossible. A huge well done from all of us at Max Energy.

The first solar electric world circumnavigation was from the East to the West. The Tūranor Planet Solar departed on 27 September 2010 from Monaco. The team followed a route close to the Equator as per the Elizabeth Swan's planned route. After crossing the Atlantic ocean, the Panama Canal, the Pacific ocean, the Indian ocean, the Suez Canal, and the Mediterranean, the ship will reach Monte Carlo with an estimated time of arrival set to spring 2012.
