MSTûranor PlanetSolar, known under the project namePlanetSolar, founded by the Swiss explorerRaphaël Domjan, is the largestsolar-powered boat in the world[2] and launched on 31 March 2010. The vessel was designed and engineered byLOMOcean Marine. In May 2012, the vessel became the first solar electric vehicle ever to circumnavigate the globe taking 584 days between 2010 and 2012.[3]
The boat was renamedRace for Water in 2015, after the name of the foundation which then operated the vessel and was dedicated to water conservation missions and to protect the oceans fromplastic pollution.[4] In 2021, new owners Porrima projects renamed the shipPorrima.[5]
In September 2022, Porrima ran aground in India and was heavily damaged.[6]
The 31-metre boat is covered by 537 m2[7] ofsolar panels rated at 93 kWp,[8] which in turn connect to twoelectric motors, one in eachhull.[2] There are 8.5 tons of lithium-ion batteries in the ship's two hulls.[9] The boat's shape allows it to reach speeds of up to 10 knots (19 km/h).[1] The hull was model tested inwind tunnels and was tank tested to determine itshydrodynamics andaerodynamics. The boat was designed to be used as aluxury yacht after the record attempt was finished.[10] The vessel was later used as an Ambassador for the project Race for Water.
The boat is registered inSwitzerland and was financed by a German entrepreneur,Immo Ströher and designed and engineered by New Zealand naval architectsLOMOcean Marine.[11] Construction cost was€15 million.[12] The nameTûranor, derived fromJ.R.R. Tolkien's novelThe Lord of the Rings, translates to "The Power of the Sun".[13]
On 27 September 2010,Tûranor PlanetSolar set off fromMonaco 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 full-time crew of four including:[14]
Additional crew members joined the voyage during select legs of the voyage including extra security in theGulf of Aden.[15]
A significant stopover wasCancún,Mexico, during the2010 United Nations Climate Change Conference held there from 29 November to 10 December 2010. 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.Tûranor PlanetSolar returned to Monaco on 4 May 2012 after 584 days sailing around the globe.
After an engine refit,Tûranor PlanetSolar broke its own record, crossing the Atlantic Ocean fromLas Palmas toSaint Martin in the Caribbean in only 22 days, four days faster than on the circumnavigation trip. The boat left Las Palmas on 25 April and arrived inMarigot on Saint Martin on 18 May. The trip led toMiami, Florida, and then continued as a scientific expedition along theGulf Stream.[16] On the return trip the boat reached St John's, Newfoundland, on 1 August 2013 before heading back across the Atlantic.[17]
