I have watched numerous videos of fast jonboats. This one is one of my favorites, http://www.youtube.com/watch?v=SaLb0-y0Fvg.

The question I have though is do these boats run a high bow lifting prop or a transom lifting prop. I have run one of Ron Hill's thru hub cleavers and the boat porpoises so bad you can't drive through it even trimmed down. I always thought high rake and bowlift were for v-pad bottoms but does that work well on jonboats too?
