Solar boat to attempt transatlantic crossing - The first solar-powered boat to attempt a transatlantic crossing has been christened and is now taking a farewell tour of European ports before setting off from Spain next month.
At 42 feet long, the Swiss-built and crewed "Sun21" was christened with Rhine spring water in Basel, Switzerland, on Monday as several hundred government officials and environmental activists wished shipbuilder Mark Wust and skipper Michel Thonney well.
"Fitted out with solar cells, batteries and electric motors, the catamaran will travel day and night without using a single drop of fuel," the team said in a press release. The team expects Sun21 to travel at 6-7 knots an hour, about average for a sailboat. The batteries store power for days with less or no sun.
