someone once said...the only diffrence in a boat with a foil and one with out....is the one with it has 4 holes in the LU
the Allys are a compleatly diffrent creature and not even closely similar to a normal V bottom boat as far as performance and set ups the foils do help some of them but i have seen a lot with out them too.....proped and set up right they dont need it and i personally dont think the Champs do either
