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.

As the speed increases, the vessel begins to outrun its bow wave. It then
has to ride over the bow wave or push through it. The faster the vessel, the
bigger the bow wave.

Sort of like the increase in mass with velocity and, as the velocity
approaches the speed of light, the mass becomes infinite. Only not exactly.
