Now THAT I find really interesting (even exciting), LUIZ (the foils in the photo). There are several things that you have done with those foils that I would like to know the effects of under actual sailing conditions, I would like to know from you just how well they work with the position of the foils so far from the tip, whether there is interaction/interference between the “wake” of the transom and the foils, whether or not their proximity to the surface effects their performance, and by using a “delta” shape for the actual foils, are they more effective at reducing “tip vortex” from the foils. There are several other lesser questions but as the foils that you have decided on are similar to ones that we considered but decided finally not to go with (mainly for manufacturing reasons), and as a consequence we did not conduct any testing on, I am more than curious as to the outcome. THEY SHOULD WORK (and work well). There are several things about your set up that I find very attractive and which I like very much, and I look forward with not a little anticipation to hearing of your “test” out come.
GOOD LUCK from down under mate, great to see an individual willing to put their ideas to the “ACID” test
P.S. They are symetrical foils?
