You are crazy to think that adding 10 mph to the top end is (a) wise
or (b) economical. these are semi-displacement hulls and the vast
majority will be squirrely above 50. Maybe with some trim tabs.
Look at Malibu's Corvette for instance.

I don't think what you call "semi-displacement" hulls are any more dangerous
than other hulls at a given speed.

I've been 82 mph in a blown Malibu, and it was quite stable...in fact, it
felt very secure.

The real issue with hot-rodding a inboard ski boat is the practallity of it.
With the prop fixed facing downward, it will always "push up" the rear of
the boat, resulting in the front going down, resulting in a higher wetted
surface.

This is exactly what high-performance boaters try to minimize...wetted
surface. Maybe that's why my buddies Malibu seemed so "solid"...it had a
good plant in the water, however, that engine would easily break 100 in a
"trimable" hull.
