If what you say about the rudders is true then why is there, or has there been, so much worrying about the design of the rudders? Rob and others have been concerned about the lower brackets being caught by waves, designs have been posted for rudders hung from the akas and there was even a proposal to hang rudders from stub akas. I'm not even talking about hanging a single rudder/daggerboard from a track on the lee hull and hauling it end to end during a shunt.
I am aware that there are other things than simple strength or turning moment involved in rudder design but it seems to be received knowledge that rudders are the "Achilles heel" of proas.

-Hi Jim, I was certainly impressed with the build when I saw 'Aroha' in the earlier stages- I even helped with a bit of the fairing on one of the rudders so it must be good! I cant see any problems with the rudders as far as slowing the boat down and Rare Bird was a good pilot study for the robustness. The brackets are strong enough to take the sailing loads so the bit of slapping won't worry them. There is not much increase in wetted area if the brackets hit a wave and it would damp even further the minimal chance of hobby horsing, which could actually improve performance. (I reckon they also provides a means of getting on board again from in the water) Coming over bars is a good test for robustness maneuverability and handling. Wish you well in the legal wrangles,and I am sure that Bain would be happy for Aroha to go to a good home, Robert--
