The Solar Sailor – the world’s largest solar vessel and the first to be totally powered by the wind and the sun – sailed for the first time into Sydney Harbor, Australia in June 2000. This revolutionary new ferry has been in service for over a year as a tourist ferry there. It uses four power sources: solar, wind, battery and a backup LPG gas generator. When fully loaded with 100 passengers it reaches speeds of 5-7 knots on solar power alone, and 10-12 knots sailing in trade winds. Solar Sailor won the gold medal at the 1999 Asian Innovation Awards and the 2001 Australian Design Awards for engineering.
