Just to add my two cents, Both boat share a similar ride height/leveling system, the Rave uses trailing wands, the Tri-foiler uses forward floats. but both do the same thing, adjust the lift on the foils to keep the boat from heeling and to not fly up out of the water. The Tri-foiler tilts the one piece L-shaped foil, the Rave has a trim tab on a T-foil, the lower drag makes the Tri foiler faster, but limits how much chop it can handle. Both of them SUCK in kelp areas, on one strong day I got a huge kelp paddy on the leeward foil of my Rave, it yawed the boat into broad reach, and if I started to go out to clear it, the boat would start to flip! Used my trusty boat hook (never sailed without it on this boat)and was able to slowly clear it, but lost alot of room downwind, glad there was no lee shore. Pitchpoled it too, it will stabilize 3 bows straight down, leaving one to carefully climb out of the **** which is now ten feet up in the air!
