So.... the answer to my question... ISAF or Nacra is pretty clear..... Gunnar Larsen responding to Bundy's snark

Gunnar Larsen
Hi Nina & Darren, Nacra 17 class is not a class to experiment with. We all know that. There is more parties involved, such as the Nacra 17 class, ISAF office and us the manufacturer. If the desire of the sailors is to spent some money on T-rudders or likewise solutions like stabilizers on the rudders. We already have the technology in place. Let's discuss this topic at the second Nacra 17 class meeting at the European championship in La grande Motte France in two weeks. Always open to talk and to recieve feedback ‪#‎empoweringsailors‬ Can you sent a formal request to the technical Nacra 17 class comite president?

Bundy acknowledges and then says ... Nothing happens until after Rio....

ISAF pooched this one.... Half baked....so they could prove they were the smartest ones in the room.... sigh....
