"Not a boat I'd want to do 60 in but it sure is solid in the low 40's!"
I agree, I am not saying 60 is practical.
Just having a little fun. Boat handles great all thru the 30's 40's and low 50's. You are probably right, aerodynamics are killing it. The console on mine is custom, modeled after a Fridgidaire then there is the t-top out there catchin wind. She was never made for the speed I am seeing now, but the hull has always been capable of speed. The wetted surface of this boat is not that different from the boats you mentioned. You probably already know this but, the steplift design as introduced by Ray Hunt on the Bertrams held quite a few records of endurance and speed. I am just proud to have what I have.
