A buddy of mine had 190rs? with a 4.6 V6. The hull they called a
Z-Plane. The thing would go 50 mph and flat water. And beat you to death
on any type of wave action.

I don't think the zhull makes much difference. I think thats more
marketing bs.
My 240cs will do 50 on flat water and is a solid ride in the waves.

Like any boat, trim tabs are what make the difference in getting on
plane and really help riding out smaller waves at speed.
