Good questions --as with anything new I suspect new coresponding ideas and techiques will emerge--just like we saw with Oracle --WOW what a show --eh ?.

Think you may have answered your own question on foils and beach wheels -the technique would be to wheel out to 1 ft water depth then slide it off --just as many do currently to save the hull bottoms .

Given the Trifoiler tri by Hobie and other foilers --see you tube clips of them } -they appear to be very easy to sail and very stable .

I,m wondering if someone hasn't already taken a CF 20 with radius boards that surface foil and added on a foil like A C boats and modified the rudder .
