huh. So it seems that the reasoning behind the "symmetrical rudder is safer" is to avoid failures of the 90 degree rudder to foil joint. I can see how this would cause a major problem if this broken during a big bear away (who knows, it may have let go during Oracle's big capsize or Alingi's) and I think it adds a little merit to the point for using them.

However, I feel like I should point out that all of them are using asymmetrical dagger boards that should be seeing considerably more loading than the rudders...soo....uhhhh.errrr
