You've confused me, Rich...
Every boat I ever owned was planing hull boat. When the boat is on plane--FULLY on plane--there's no bow wake and very little stern wake. It's only when the boat anywhere in between idle speed and full plane that there's wake...increasing as rpms increase until the bow "falls over," then immediately reducing to a stern wake so flat it's not even noticeable except visually (scares the hell of sailors who only see a fast boat without noticing how little wake, though). It's the big displacement boats and planing boats that are running with their noses in the air that make the most wake.
We've always considered "hull speed" to be the max speed through the water at what can be considered max idle speed...iow, the fastest an individual planing hull can move before its bow starts to rise and its stern starts to dig in and make wake. And calculated it using 1.3333 x sq. rt. of the WLL.
You're saying that's inaccurate...but if the boat ain't makin' any wake, how do you calculate the speed of any planing hull that's moving within "idle speed" range?
