Luiz, by V foil that is what I meant, there is no good way to describe it with keyboard symbols though...maybe I should have used the \o-O-o/ for the symbol? But I meant what is on that thing up above, I guess it's a Bruce foil.

BTW, the Hobie 18 I was refering to had two foils that looked like an upside down A or a V with a cross foil, like a V shaped ladder where the rungs were also foils. One was mounted on each hull just forward of the main beam and they could pivot up for launching and trailering.
