I think the "scientific" talk should be left at home. I don't think anyone has designed working airplanes, much less a widely used sailboat or rig. Until that happens, your various theories don't hold a whole lot of clout.

First of all, if you have ever sailed a boat with wings you should know that wings do help. I am not going to argue how efficently they help, but they do help control.

Second, major break throughs will not happen anymore with "beachcats". People like them simple. The vast majority of sailors will not buy new & possibly complex technology just to get a extra 2-3mph. Until you can land a tri-foiler on a beach, the majority of beachcat owners will stay with what works. Look at the H16. It isn't even that fast, but it sure is popular.

Simple + fun = sales
Complex + new = less sales
Complex + new + over $12K = almost no sales

If there were a market for "new breakthroughs" then someone would come up with something.
