On my run this morning I noticed some of the yachts for America’s Cup preparing for an event.  The cup isn’t until 2013 but I hope to get to see a few of these up close and in action.  As a former aero engineer I find these yachts fascinating.  They operate at the boundary of two entirely different fluids, and these yachts don’t just operate, they perform exceptionally well.  I remember the 12 meter yachts from the 80’s and being interested in them then.  The IACC yachts today are less traditional in appearance but still amazing.
