Catamaran to circle the globe on solar power alone
‘She is finally away – Planet Solar’    .

Last week, on Monday 27th September, after many months of planning and construction, a very large solar solar-powered yacht called Planet Solar set out from Monaco on a 31,000 mile trip around the globe. Its goal is to be the first to circumnavigate the globe in a ‘solar’ boat, i.e. one powered by a silent, pollution-free electrical engine, driven exclusively by solar energy.

It is estimated it will maintain an average speed of 7.5 knots per hour. At that speed it should take about 160 days to travel around the planet.

The multihull will be home to four sailors during the round-the-world attempt, and can accommodate up to forty people during the promotional trips planned at each port of call.

That our planet deserves a better, brighter and less polluted future. Future technologies must be keenly investigated and solutions must be found. The project will help to motivate engineers and scientists to develop innovative technologies, inspire people around the world, and show that the impossible can become possible.

About Planet Solar:

The vessel itself, PlanetSolar, is a multlihull vessel topped by a large array of photovoltaic solar panels, constructed by Knierim Yacht Club, in Kiel, Germany. Additional removable parts allow it to expose a total of 537 m2 of photovoltaic surface (solar panels) to the sun.

This impressive data make it the biggest solar run ship in the world.
Built in 14 months, the boat has impressive dimensions and is yet both silent and clean. Its goal of circumnavigating the world at an average speed of 7.5 knots is no mean feat for a solar-powered craft.

The boat’s top covered with the photovoltaic solar panels gives it a capacity of 93.5 kilowatts of electricity. It cost about $13 million to construct and was funded by Rivendell Holding AG, a Swiss company renewable energy investment company.

Subject to change, stopovers will take place at the following cities: Miami, Cancun, San Francisco, Sydney, Singapore, and Abu Dhabi:
