The Microtransat Challenge is a transatlantic race of fully autonomous sailing boats. The race aims to stimulate the development of autonomous sailing boats through friendly competition. The first transatlantic race was due to start in September 2009 from County Kerry, Ireland however all but one team have now said they aren't ready and the race has been canceled, details of the 2010 competition will be released soon.
These self sailing vessels are amazing. Complete with GPS, wind sensors, tilt compensation, solar power, radio, and more! I haven't got around to checking everything out, but a few are even open source. Not only do these boats have to sail across the Atlantic, but also race! I'd like to identify the code where there is calculations for velocity made good, a necessity to accurately trim sails, adjust heading, and maximize potential. Think of the potential piracy of such a defenseless investment floating in the middle of the ocean. P]
