Rolf, but if we ban them once someone has spent (a lot) of money on developing them they will not be happy; if we just ban them then the problem goes away.

I firmly believe they will give a considerable andvantage upwind as you can create RM and a massive advantage downwind as you can wind on the anti-pitchpole when you need it. I just feel they are an expensive and complex system that will give gains and if we don't ban them we will be sailing obsolete boats. I do not believe that the tip weight on the mast difference is so great.
