The official website of the competition says, "the greatest challenge is to show that you do not need to live in a sun-drenched tropical country to be able to generate and apply solar power."

Participants include universities, schools and companies from all over the world to compete in the most innovative solar-boating race in the world.  The course has been extented since its first debuted in 2006 as the boats have become faster. The competition wraps up on Saturday. Prizes will be given for best design, innovation, bad luck and fair play.  More information about following the race can be found on their website.
