Well if this does prove to be a real improvement in speed, then I would say that many of the top competitors in the class will look at modifying their boats. I though that Lars was playing with banana foils last year or the year before around the time that he convinced me to join the class. As to Ben's rig, I thought that downwind he was doing extremely well, but was struggling to find speed upwind and in certain wind conditions. I may have it bill, since you are active in the fleet and I am not.
