Has anyone seen what brought an end to A-class development in this? Rules? Drifting conditions downwind when some degree of bow down often is used to reduce transom drag.?
Would be interesting to see what was the reasoning for abandoning it as it seem to be very promesing.
As far as I know, the A Class initially banned rudder foils similar to mine. They were close to the surface and the concept was that they would increase the effective waterline. They probably worked well, otherwise it wouldn't be necessary to ban them.
I don't remember where I read this, so take it as an unconfirmed rumour.
