Default Whatever Happened To "Cathedral" Hulls?

I have one - it's a 16 foot 1969 Vanguard made in Canada with a
85hp.Evinrude. It has a stepped hull like the Regal fast-trac. It is quick
to plane and goes 41mph with a 17" pitch prop. I wonder how fast it would
go with a 19" or 21" prop.

I think the shape and the steps help get air under the hull and boost
speed. It pounds like crazy in even small waves. I once made a sharp turn
at full speed and the inside corner dug in and it cornered like an F1 car -
scared the hell out of me because I figured if it let go part way through
it would have flipped. If I would have had a passenger they would have been
thrown out, the turn was that sharp. I guess that's neat but I haven't
tried it again.

It goes and handles well with just 2 passengers but when I have a total of
5 people aboard it uses over twice the gas and handling is very sluggish,
more so than other boats. Maybe that hull is more sensitive to load then
deep-V's.
