Actually, I think the results are a mixed bag of issues.

firstly, no team would attempt using a new technique or piece of equipement in an Olympic regatta without first knowing it would provide an advantage. Team USA, NED and PUR were all testing this sail as partners for over 1 year and were convinced in it's potential.

However, it seems to have a tight performance range and the added benefit in the relatively shorter races seems marginal.

Finally, the venue has lived up to expectations...not only light winds, but highly variable pressures/directions. Just look at the wide swings in the fleet mark roundings in most of the races.

I agree it appears the code zero Chupacabra has not workout for team USA, but I also don't think this regatta is a satifactory test of it.
