He He...

I did not say the center boards need to go forward... Bert Did
I did not say the boat needs winglets... Bert Did.
I did not say the boat has occasional stability issues Dave did.
The Canadians were using the carbon stick for the first time and it is different dynamically then the alu stick. I infer the boat has stability issues with all their crashes and they are working through them... basically Dave is right.

All I want to know is why the boat is not being modified ASAP given its olympic status by ISAF. Hell... you can get winglet kits now and mod your own rudders in the A class in a weekend.
