About the Race for Water solar boat

This ship is the largest catamaran in the world powered by solar energy. On May 4, 2012, after 584 days of sailing, he completed in Monaco the first world tour exclusively driven by solar energy, under the name of MS Tûranor PlanetSolar. Following this unprecedented achievement, work is carried out in 2013 to give the catamaran a second life as a scientific and educational platform.

In 2013 and 2014, the PlanetSolar DeepWater (study of the Gulf Stream) and PlanetSolar TerraSubmersa (exploration of submerged prehistoric landscapes in the Gulf of Nafplion) scientific campaigns are launched in collaboration with the University of Geneva.

In April 2015, the MS Tûranor PlanetSolar is offered to the Race for Water Foundation, a charity which aims to preserve water. She is then renamed Race for Water solar boat and her role is redefined around new missions focusing on the issue of marine litter. The ship is currently undergoing transformations to be operational for her future missions.

The ship’s scientific campaigns

In 2013, the largest solar catamaran ever built crossed the Atlantic for the second time within the context of the PlanetSolar DeepWater scientific campaign. Led in collaboration with the University of Geneva, this expedition aimed to explore oceanic processes interacting with the atmosphere by taking measurements in air and water on more than 8000 km along the Gulf Stream. 

Following this successful campaign, the ship moored for the first time at the Cité de la Voile Eric Tabarly in Lorient during the winter before “setting sail” again for a new campaign.

In 2014, the catamaran travelled 9000 kilometers and stopped in 8 cities to promote solar energy. The highlight of this 2014 campaign was the PlanetSolar TerraSubmersa scientific expedition. Initiated by the University of Geneva, this archeological mission aimed to study the submerged prehistorical landscapes in the Bay of Kiladha. Thanks to her spacious living space, full energetic autonomy as well as her low draught, the ship has been a perfect platform for the scientists.

Since then, the ship has reached Venice end of 2014 for her wintering and then sailed towards the Cité de la Voile, where she arrived in July 2015. The catamaran will be docked in Lorient until the end of September. Several transformation works will be operated in order to prepare the ship for her next expeditions with the Race for Water Foundation. This charity is dedicated to fighting against plastic pollution in the oceans and is currently conducting a scientific expedition to assess marine litter in all of the oceans – the Race for Water Odyssey. The conclusions reached will allow the Foundation to launch campaigns to fight against this plague and to better manage plastics end-of-life. Race for Water solar boat’s key role will be used to present on board plastic waste upcycling solution demonstrators. What is more, she will continue playing her role of scientific and pedagogical platform with full energetic autonomy.

Planetsolar arrived in Lorient for the summer


After an eventful and sunny stopover in Marseille (see here), the PlanetSolar ship set sail (or better said,switch on its solar powered engine) towards the Cité de la Voile Eric Tarly in Lorient, where she already spent her winter in 2013.

Before this stopover, where she will undergo maintenance works as well as some transformations for its 2016 campaign, the largest solar boat ever built stopped in Concarneau. This stop consisted in dry-docking the boat for 2 weeks. This operation had two main objectives: maintaining the fairing with a new antifouling and the inspection by the DNV GL (Det Norsk Veritas, Germanischer Lloyd), international body of certification. Dry-docking a boat is always a technical and precise manoeuvre. Thanks to our technical team (Lia Ditton and Jean-Marc Normant specifically) and to the expertise of the captain Gérard d’Aboville, the entire operation went smoothly. The quality of the floats surface was remarkable thanks to the hydro stripping which was applied as soon as the boat was dry-docked and thanks to the support of our partner International Peinture SA, which supervised these works with a meticulous monitoring.

PlanetSolar arrived last night in the Cité de la Voile Eric Tabarly and will remain there until the end of September. Visits of the ships will be organized in collaboration with this unique museum, for the public who wish to jump onboard in order to discover the boat as well as get to know more about solar power and renewable energies. 


PlanetSolar greeted by François Hollande and Albert II, Prince of Monaco, at the MEDCOP 21


Leaving Venice on 22nd May, the largest solar catamaran in the world arrived in the Phocaean city on Wednesday. En route for Brittany, where it will carry out maintenance and transformation works in view of its upcoming missions under the leadership of the Race for Water Foundation, the ship makes a stopover in Marseille to take part as a guest of honour in the Mediterranean civil society forum for the MEDCOP 21 conference. The President of the Republic came aboard and was very impressed by the vessel and her actions in favour of the environment.

Moored in front of the Mediterranean Villa and the "Village of Solutions", which highlights projects and initiatives based on managing climate changes in Mediterranean countries, the largest solar catamaran ever built will assume its role as Clean Energy Ambassador, by hosting conferences and events onboard throughout the whole week.

The MS Tûranor PlanetSolar leaves Venice and starts its 2015 campaign


The MS Tûranor PlanetSolar will leave Venice tomorrow after an 8-month winter stay on Certosa Island. This departure marks the start of a new campaign, which will mainly consist of reaching Brittany to perform maintenance and transformation works in preparation for the boat’s next missions commissioned by the Race for Water Foundation. On her route, the largest solar powered boat in the world will make a stopover in Marseille in order to participate in the MEDCOP21.

Docked in the Veneto region of Italy since the end of her TerraSubmersa scientific expedition in September 2014, the MS Tûranor PlanetSolar will return to sea on May 23, 2015 and begin a new solar campaign. This represents the boat’s first navigation under the Race for Water Foundation’s flag, owner of the boat since mid-April 2015.

The largest solar catamaran ever built will get to the heart of the matter by dropping the anchor from June 3rd to 8th in Marseille, the first stopover of this campaign. In this ancient Mediterranean city, PlanetSolar will be the guest of honour of the MEDCOP21, the Mediterranean civil society forum on climate.

During the event, the vessel will be docked in front of the Villa Méditerranée, which will host the “Village des Solutions”. This area will be opened to the public and will aim at raising awareness about the stakes linked to climate change in the Mediterranean region. PlanetSolar has been invited to actively take part in this event as a photovoltaic ambassador and as a successful example of the use of clean energy.

After this event, the MS Tûranor PlanetSolar will continue her journey to Brittany, where maintenance works and some modifications will be performed. These modifications will be made in order to make the vessel operational for her next expeditions, which will be focusing on the issue of plastic pollution in the oceans. Gérard d’Aboville, Captain of the catamaran, feels very concerned about this ecological disaster and is looking forward to participating in these new missions:

“Throughout my career I have unfortunately witnessed the degradation of the world's oceans and this cause is thus very close to my heart. We must preserve the oceans against this plague of plastic pollution. I am looking forward to these new missions aboard the MS Tûranor PlanetSolar in the service of this cause.”

The maintenance work will, among others, be performed in the Cité de la Voile Eric Tabarly in Lorient (France). They will allow the vessel to play her role as a proper scientific platform once more, following the success of her previous DeepWater and TerraSubmersa expeditions.

PlanetSolar is getting ready to set sail again!


PlanetSolar is getting ready to set sail again!

After an 8-month wintering in Veneto, and more precisely in La Certosa, the MS Tûranor PlanetSolar is about to return to sea. Property of the Swiss Race for Water Foundation since mid-April, the largest solar-powered boat in the world will indeed leave Venice in the very near future. This much awaited departure will mark the start of a brand new solar campaign for the PlanetSolar and Race for Water teams.

Still under the leadership of the historic captain of the MS Tûranor PlanetSolar, Gérard D’Aboville, the entire crew reached Venice in the last few days to assist with the preparations of this new campaign. Final technical verifications and logistical preparations are currently being conducted in order to navigate in the best possible conditions.

For her new 2015 adventures flying the Race for Water’s flag for the first time, the MS Tûranor PlanetSolar will host “old acquaintances” as well as new crew members:

  • Gérard d’Aboville - Captain
  • Brieuc Delbot - Second
  • Alain Craniotakis - On board engineer
  • Aurelia Ditton - Deck Hand, electrician assistant
  • Vincent Brunet - Deck Hand, logistics

Where will PlanetSolar stop first for this 2015 campaign? The PlanetSolar and Race for Water teams are excited to share this with you next week!

PlanetSolar receives the Green Pride award!


On May 7th, the UniVerde Foundation awarded PlanetSolar SA in recognition of its best practice in the field of clean energy. The Green Pride prize is presented annually by this Italian foundation, which promotes sustainable development, to honor companies for their excellence in this field.

The official award ceremony took place aboard the MS Tûranor PlanetSolar, which is docked in Certosa Island since the end of her 2014 campaign. For this event, M. Alfonso Pecoraro Scanio, President of the UniVerde Foundation and former Italian Minister of the Environment, as well as other members of the foundation’s scientific board were welcomed aboard the largest solar catamaran in the world. Brieuc Delbot, second of the MS Tûranor PlanetSolar, received the Green Pride award from the President’s hands on the solar deck under a glorious sunshine.

The Race for Water Foundation, owner of the MS Tûranor PlanetSolar since mid-April, is proud and honoured to have been awarded such a prize, a recognition which closes in style the wintering of the catamaran in the Venetian Island!

The MS Tûranor PlanetSolar Has Been Donated to the “Race for Water” Foundation and is Getting Ready for Innovative New Expeditions


Docked in Venice, the MS Tûranor PlanetSolar is preparing to return to sea for a new mission. Announced in September 2014, the search for a new owner who would be able to continue operating the ship began in September 2014 and has been successful. After only a few weeks of discussion and one meeting in New York at a United Nations conference, the Ströher family decided to offer the solar catamaran to the Race for Water Foundation, which is committed to pursuing the ship’s operation in service of the environment.

The Race for Water Odyssey is a scientific sailing expedition that aims to draw up a comprehensive assessment of plastic ocean pollution. Marco Simeoni, the Race for Water Foundation’s President, is currently in New York, where the expedition has made a stopover. Delighted by this donation, he is very touched by the confidence the Ströher family has shown. Grateful, he reveals his vision of the solar ship’s future:

“I aspire to equip the MS Tûranor PlanetSolar with a mobile laboratory for collecting and analyzing plastic litter in order to fight against ocean pollution. The history of this unique boat and the enthusiasm she generates at each stopover are powerful communication tools that I would like to put to good use to further the cause for water preservation. Moreover, this ship represents a wonderful pedagogical platform.” 

The Ströher family is happy to have found the Race for Water Foundation, a successor with similar values that is capable of sustainably pursuing the ship’s operation in service of environmental preservation.

“PlanetSolar’s objective, on one hand, was to conceptualize an idea that would prove the efficiency of solar technologies, and help in their growth and promotion. And on the other hand, it aimed to demonstrate that above and beyond a technological feat, the ship could be used for practical purposes in connection with sustainable development,” stated Immo Ströher, patriarch of the family.

Thanks to the businessman’s financial commitment and significant personal investment since 2007, PlanetSolar was able to go well beyond its initial accomplishment—completing the first exclusively solar-powered trip around the world—to create a sustainable company with a strong brand and international notoriety.

This donation arrived at just the right moment. In fact, the “Race for Water Odyssey”, initiated by the foundation, is in full swing and extensive new scientific data has already been collected. Thanks to this donation, the foundation will be able to start making preparations for the MS Tûranor PlanetSolar’s future campaigns. The ship’s operation has been entrusted to PlanetSolar SA’s experienced teams, that are working in parallel for the promotion and deployment of renewable energies.

A PlanetSolar WebDoc !


Dear friends of PlanetSolar,

As we near the end of 2014, a brand new kind of documentary has been devised by ARTE, RTS Discovery and Souris Verte, which looks back at the PlanetSolar adventure from its very beginnings. Get ready to dive into the world’s oceans, and experience the adventure as if you were there!

But what is a WebDoc ?

A WebDoc is a documentary that is intended to be interactive, thanks to online multimedia content. Unlike a traditional documentary, in which you have no choice but to follow the producer’s predetermined narrative, a WebDoc allows you to navigate and experience the story on your own terms.

With this WebDoc, you can completely immerse yourself in the life of the MS Tûranor and PlanetSolar.

An interactive platform lets you return to the highlights of the PlanetSolar adventure. You can navigate the story by theme, and immerse yourself thanks to narratives, animated sequences, soundtracks, and numerous illustrations.

This unusual amount of freedom lets you interact with the subject on your own terms, by turning the viewer into the main actor.

Ready ?

Are you curious and ready to discover what the PlanetSolar WebDoc really looks like?? Click on the link below to climb aboard the MS Tûranor PlanetSolar!

PS: Unfortunately, this exclusive Webdoc is only available in French and German. We apologize to our English-speaking friends.

Our winter stay in Venice continues… and we wish you happy holidays!


The ship is docked on the island of Certosa, far away from the tourist-packed streets of Venice. To get there, you sometimes have to brave this year’s particularly strong Aqua Alta. During the cold season, the boat’s immense and futuristic curves only reveal themselves up close.

Visitors discover a ship that is far removed from her source of energy. Despite a sky that is (too) often scattered with grey clouds, the MS Tûranor PlanetSolar’s cobalt blue solar panels gives her a strange silhouette that looks more like that of a spaceship. Although Helios is occasionally making his absence felt, visitors are still just as awestruck when visiting the ship’s solar deck!

During this time, the land crew is taking advantage of the winter break to get a head start on their next adventures. In fact, always keen to diversify its activities, PlanetSolar SA is working with partners to develop autonomous energy systems, meaning solar panels (or other sources of renewable energy) that connect to a storage system (batteries). These developments are notably very useful for isolated sites that are not on the grid.

In other news, we announced in September that the ship was seeking a new owner. We are now currently reviewing several interesting proposals, which we will share with you soon.

Finally, if you are still on the hunt for Christmas present ideas, we would like to remind you that it is still possible to come visit the MS Tûranor PlanetSolar during her stay in Venice! Whether you would prefer an evening on the ship, a technology-focused visit, or a cocktail aboard, please do not hesitate to get in touch with us. ;-)

On that note, we would like to wish you a very happy holiday season, and we look forward to sharing more solar news with you soon!


PlanetSolar makes a remarkable entrance in Venice (Italy), and starts searching for her next owner !


Launched on April 13 in Boulogne-sur-Mer (France), PlanetSolar’s 2014 campaign comes to an end today, in Venice, the boat’s last stop and prestigious winter home. This 9,000 kilometer trip, spread out over 5 months of navigation, featured stops in Atalayoun (Morocco), Monaco, and then Greece, where the ship transformed into a scientific platform as part of the “TerraSubmersa” archeological expedition, led by the University of Geneva (UNIGE). Once again, the largest solar-powered ship ever built showed she could be used for concrete goals, and thus reaffirmed her position as a multi-functional tool and formidable communication platform. Now at her peak, the ship searches for a new owner.

PlanetSolar’s 2014 campaign ends today, on a high note. Through the course of these past 5 months, the largest solar-powered ship in the world has reaffirmed her position as a multi-functional tool, and has definitively confirmed her incredibly important use as a scientific platform, launched in 2013.

During 8 stops spread out along a 9,000 kilometer route, the solar-powered boat met with the public and carried out her mission of promoting solar energy. The high point of this 2014 campaign was the “TerraSubmersa” scientific expedition, which took place in Greece during the month of August. Carried out by the University of Geneva (UNIGE), this mission aimed to explore the prehistoric landscapes that have been swallowed up by the waters of the Kiladha Bay, in order to reconstruct them and identify potential traces of human activity. For more information, about TerraSubmersa, click here.

Thanks to a partnership with Vento di Venezia (VdV), the organization responsible for promoting the Island of Certosa (Venice), PlanetSolar will spend the winter in the Serene Republic. During this period, which will last until May 2015, VdV and PlanetSolar will jointly organize public visits and private events. To celebrate the end of her campaign, a series of activities will be organized around the boat from September 4 to September 9.

PlanetSolar seeks a new owner

The MS Tûranor PlanetSolar adventures have been due to the Stroeher family (boat owner), a German family that is passionate about solar technologies, and has been operating behind the scenes since the start of the project.

“The goal was on the one hand to conceptualize an idea that could prove the effectiveness of solar technology, and would help promote and develop that sector. On the other hand, we also wanted to demonstrate that beyond her technical prowess, the ship could be used for concrete, useful goals,” explains Immo Stroeher, the family’s patriarch. The businessman’s financial investment, as well as his significant personal engagement, has allowed PlanetSolar to go much further than a single trip around the world, in creating a durable enterprise that now allows the ship to be used for concrete goals.

“The MS Tûranor PlanetSolar, winner of 6 Guinness World RecordsTM, not only completed the first solar-powered voyage around the world, but has also successfully carried out two unique scientific missions in 2013 and 2014, both of which were punctuated with prestigious stops during which countless visitors were able to visit the interior workings of the ship! Today, we are very proud to note that after the success of her voyage around the world, PlanetSolar has undergone a perfect transformation, carrying out not only scientific missions, but also serving as a powerful tool of communication thanks to the enthusiasm she generates at each stop. Our expectations have been exceeded, and it is time for us to retire, and pass this unique ship on to a new owner.” Immo Stroeher concluded.
