Funny thing is, that she would probably do 42 kts with 50,000 HP and
the next 2 knots would take 3 times as much. Such is the rule of
displacement vessels. To take that one theoretical step further, if
they wanted to go 46 knots, they's need 400,000 HP. 47kt 1 million. 50
kts a bezllion HP
I think 55 knots or so is the theoretical maximum a vessel can move through
the water, irrespective of the power pushing it.

Nope. *not even close

Currently, unlimited power-boat races are in the 160MPH range. in years past,
they got up into the 200 MPH range, but engine/fuel restrictions have brought
the speeds down.

'Cigarette' boats can reach 80+knots in calm water.

Some torpedoes -- which travel entirely underwater -- have sustained speeds
well over 100 knots.

unlimiteds aren't displacement boats, they're hydroplanes. *Cigarette
boats are also on plane at speed and therefore not displacement vessels.

I can't wait to see the next hydroplaning aircraft carrier!
