    Be careful not to take out too much....it is a balance of weight and speed. Too heavy or too slow and you have a dog. Designing hydros optimally means designing for a relatively small speed window. Then we have the wind.........

              If I get too much lift I'll try moving it forward from here.

                Tried the tape method on my Motley today, don't think it did a thing! Looked for some old straws in the truck but didn't have any. So far I like the wiper held on with 2 sided tape. Been working good for a while for me.
                Had the same amount of porpoise with or without the tape, just a slight bob about the last 1/3 of the straight. Wiperblade and it was back to smooth and the amp draw went down 5 amps average for the run. No other changes at all.
                If my boats upside down then who owns the one I thought I was driving the last two laps?

                  Decided to move the dam up a bit, see pic. Did 3 runs today-- worked really well. Ran full throttle in the turns, and even when the water got choppy with the other boats it stuck nicely.

                    Nice work. Very close to where mine is.
                    Interesting the way your sponsons are.
                    Tweak here and there is what makes these boats run much much better.
                    6months of fiddling and finally feel like I have it where I want it.
