Tell me, does this "sine function" quoted in the "theory" of hull speed have
anything to do with the concept that the hull makes waves and the "sine
function"
also has something to do with waves?

not at hull speed, it doesn't.

the following is bull ****!! (two words), for among other things dougies
doesn't know what the word means and there is in fact no (none, zero, zip,
nada) asymptote at hull speed (there *is* at infinite boat speed, but that is
not usually a consideration)



As for the asymptote, the usually quoted hull speed is in fact an asymptote
of the
combined resistance graphed against speed of a given hull. It has a lot more
to do
with the "theory" of hull speed than any sine function.

But you don't want facts, do you Jax? They seem to make you uncomfortable.
