They need to get back to sailing by human hand only. To me electronic controls fall in the same area as any other non human power system system. It equates to putting traction control computers on race cars. It is no longer the sailor sailing the boat. It takes a lot more skill to trim sails when you a grinding them in and out vs charging a hydrolic system the pressing a servo switch to trim in and out. Technology is great but lets keep the cup a SAILING race for SAILORS.
I agree, if they would bring it back to the 45 footers, soft sails, nationality rules, and allow full foiling, they could do it all by hand, with no hydrolics or electrics allowed or needed.
I know that would be a step backwards, in development, but if they really want 10-15 teams to show up, they are going to have to reign in the costs.
