TÛRANOR PLANET SOLAR - Solar Catamaran

TÛRANOR PLANET SOLAR is the first catamaran to sail around the globe powered exclusively by solar energy. The innovative boat left the Knierim yard in August 2010 for extensive sea trials leading the boat from the Baltic Sea through the North Sea, the Channel, and the Bay of Biscay down to the Mediterranean. This trip has been finished successfully, all systems worked well and the hull proved to be very seaworthy.

The boat started its circumnavigation on September 27, 2010 in Monaco and finished it in May 2013. Stops were Miami, Cancun, Cartagena, the Galapagos Islands, before the boat crossed the Pacific and arrived safely in Brisbane, Australia. Returning later to Monaco via Singapore, Hongkong, Abu Dhabi. Stop overs have been made to introduce the project to as many people around the world as possible and to raise awareness for sustainable energy.

TÛRANOR PLANET SOLAR is a trendsetting master piece regarding the use of solar energy and storing the power over a longer period. Thanks to Knierim’s outstanding experience in building one off boats all technical requirements for this prototype have been executed to the owner’s satisfaction.

TÛRANOR PLANET SOLAR has a length of 31 meters by a width of 15 meters and a displacement of approx. 60 tons. To collect sufficient energy for the electric propulsion the entire deck has been covered with solar moduls plus retractable wings, totalling to a surface area of 537 square meters with 825 solar moduls and 38,000 photovoltaic cells. The energy is stored in lithium ion accumulators with a capacity of totally 1130 kWh. The accumulators weight is 11.7 tons. The energy is transferred into 4 electric motors with 240 kW each. The engines are connected to 2 shafts with surface propellers, which are rotating very slowly but have a high torque.
