Planing boats have the same limit, in other words as they go faster,
each incremental increase in speed takes an increasing increment in
power. Eventually the power/speed curve gets just as steep as
displacement hulls...
Until you get past Mach 1, at least! ;-) after that point,
there are some inflection points in the power/speed curve, IIRC.
In any case, ALL power/speed curves seem to be asymptotic
to c (speed of light).
How's that for a 'reductio ad absurdum' argument?
What you describe is not an asymptotic relation.
?
Looks like it to me. It's just much farther to the right on the graph
And on a Very large graph!
