comments interspersed.

Is it your position that drag on the hull does not increase with
speed?

the induced drag on a hull goes up at the cube of speed and has nothing to
do
with "climbing the bow wave". A cubic function is mathematically well
behaved,
meaning nothing untoward happens anywhere on the curve.

Then it follows from observation of this well behaved curve that,
given sufficient horsepower, a displacement hull is not limited in
speed.

this is true, though a cube function explodes in magnitude. But it does so in
a mathematically well-behaved way.


Or perhaps, to put it another way, the wave system created by the hull
passing through the water is not limited in speed, either.

specious arguement unrelated to the discussion.


Thus, given the mathematical example, both the hull and the associated
wave system could travel at, say, 45 MPH for a 25 foot boat ....
assuming adequate available horsepower.
