Sailbot-scale boats are way too small to do the Microtransat. I love to see the effort, as I know first-hand the challenges of making a boat sail autonomously. But my prediction is that the only way anyone will complete the Microtransat is with a large hull and a tried-and-proven rig, like an Optimist dinghy. But like I said, I love seeing people excited about robotic sailing, so congratulations on your work so far!<p>Source: I'm part of the autonomous sailing team that won the 2012 World Robotic Sailing Championship (WRSC) and made Best Student Team last year. Our boat is 2,5 m long with around five years of work poured into it and I guarantee it can't cross the Atlantic unless it catches a lucky break.
