Going 100+ mph, even more so at 150+ the running surface is considerably shorter, the front steps are lifted from trim and Rocker (if any) and only the last step or two are contacting the water, the Angle of attack on the steps to the water at that speed is pretty much identical being 0* to 3* or 4* Maybe 5* degrees. I say they both have about 10' of running surface going that fast, the 43' or 41' becomes irrelevent. then power and aerodynamics take over (and Balz)
