The more I think about proa rudder issues the more I like the twin foil steering concept by Fulgencio that has been presented in proafiles: http://groups.
Downside of the concept is that it is not enough to have that system alone. It would need a rudder for downwind sailing and motoring, which means there must be additional foils. Of course the twin foils system with two rudders would provide all the steering you need. Adds complexity and weight though.
Many of the problems in harryproa concept seems to be related to the placement of rudders. Placing rudders in the hulls should make them more effective and also have the force vectors more balanced than placing them between the hulls.
