Nutsy,

You really are full of ****!! Really!

Theoretical hull speed is a precise measurement and generally close to
the mark. ----This is your statement! Read it again.

Theoretical;----Is a precise measurement?? Spare me.

Generally close to the mark;-----this is what you call a "precise
measurement!"
What a dumb ass statement.

Nutsy; I think you had better find out what "Hull Speed" is all about!
It seems you haven't a clue!
