Today's keynote was Thiha Win, one of the designers of BMW Oracle Racing's America's Cup boat. Great study fo cutting edge technology done with ProENGINEER and Windchill amongst other tools. Lots of FEA, CFD and laser analysis of wind pressure too. The stress on the lines supporting the rigid "wing" sail ran as high as 30 tons! Thiha mentioned once a pin gave way, and was shot into the mast embedding itself there. Yikes. See more here: http://bmworacleracing.com/en/yacht/index.html
