Nope. On the trifoiler, both windward and leeward foils seek a fixed depth, thanks to the forward "sensors." In lighter winds, both foils generate positive lift. In high winds that would otherwise capsize the Trifoiler, the windward foil generates negative lift to seek the target depth
Have a read of the tri foiler manual. I put the link on the last posting. In it Ketterman explains why the leeward foil rises. You will find it interesting. Or maybe have a go on a tri foiler! <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />
