There's no doubt foiling is the craziest feeling in sailing, I took a buddy on my Rave, and he was blown away, and he got some good runs in on his first time driving. For sure the tripod arangement is easier, but outlawed in Moth class. I have seen a few cat mods with flip down foils at the bows and an additional center rudder with foil at the back. The Rave is a bit heavy, but while demoing the first time in San Diego I watched my buddy hit a sandbar at full speed, almost flip it over the bows, come back to the beach with one ama crumpled up, and by the next day the plastic had straighted itself out, so it has good real world sturdiness. One time I launched it off the back of one swell into the face of the next one, and went so far under water it was getting dark overhead, and the boat just kept on going! ( man that bilge pump is handy. The Moth with foils has to be the toughest boat in the world to sail as the tiller also twists to control the rudder foil pitch. But as noted the major drawback has got to be no surf lauching. Nothing like charging into the lineup on a big wave day...
