Sun and Water: Zero-Emissions Solar Cruising

    Solar Boat

    At almost 20 tons, PlanetSolar is the world's largest solar-powered boat, built with close to 5,600 square feet of solar cells. On its recent mission across the Atlantic, titled the PlanetSolar DeepWater expedition, the boat's crew gathered physical, chemical, and biological data that will be used to better understand interactions between the ocean and atmosphere. The data may also be used to model climate conditions and help biologists understand plankton and other forms of ocean migration.

    Launch Day

    Last year, PlanetSolar sailed for 584 days and completed the first solar-powered trip around the world. After that trip, the ship underwent major maintenance operations. This included the most significant change—the surface propellers are now completely submerged.

    First Leg

    The first leg of the journey was from the south of France to the coastal city of Rabat, Morocco, via the Mediterranean Sea and through the Strait of Gibraltar. The researchers were particularly interested in ocean vortexes—a phenomenon of large whirlpools that break away from the Gulf Stream and influence heat exchanges with the atmosphere and phytoplankton growth.

    Arriving at the Bouregreg Marina in Rabat, PlanetSolar's carbon fiber and epoxy resin hull cuts through rough seas. There were five crew members on board for the transatlantic journey, with an onshore crew of eight, including logistics managers, marketing, security, and the expedition’s medical doctor. Dr. Pascal Goulpié, the managing director and co-founder, was often at the mooring site to provide tours of the boat. When docked, the ship can hold 60 people.

    Longest Leg

    After Morocco, the ship stopped in Las Palmas on the Canary Islands, then made its longest trek without stopping. Over the next 22 days, it traveled about 3,100 nautical miles (3,600 miles) to the island of St. Martin in the Caribbean, setting a world record for the fastest transatlantic crossing by a solar boat.

    Destination New York

    On June 17, the catamaran pulled into New York City’s North Cove Marina after sailing under the Brooklyn and Manhattan bridges. It had traveled from Miami, where the DeepWater expedition began its measurements of the 5,000 miles of the Gulf Stream. This ocean current helps carry heat from the tropics to the polar regions in the North Atlantic, making it one of the most important regulators of the European and North American climates.

    Departing for Home

    The northernmost point on the voyage was Port Saint John in New Brunswick, Canada. Before crossing back to Europe, technical work was done on the boat and the scientific crew changed.

    Tight Fit

    PlanetSolar traveled through the English Channel and headed toward Paris via the Seine River. Along the route there were some tight squeezes under bridges and within channels. The boat is 82 feet long, 75 feet wide, and 21 feet high. The design includes flaps on the sides that can be drawn in, reducing the overall width by 25 feet.

    Winter Rest

    PlanetSolar came to rest in Lorient, in the north of France, on Sept. 25, and will be on display there until March 2014.
