Beats me. Maybe you've got a better incidence between wing and float than I have, but both of mine were murder before I relocated the floats so that the CG was 1/4-1/2" aft of the steps. The little Heinkel wouldn't even plane- it just tried to push the float bows under the water. The Superstar wanted to porpoise along the water until I fixed it.

I do know one thing for sure- you won't find any planing hull boats with the weight bias forward. Too much weight in the bow, and a planing hull won't
