[Rhodes22-list] Measured Hull Speed

[Steve]

Hey Roger, I have a very scientific methodology; (your
gonna love this); I have found that with the proper
amounts of Beer & bourbon; It just don't matter:-)

Actually, here in Arkansas, we are pretty helpful to
one another.  If someone run out of fuel, we pull them
in.  Most people here only require a 6 pack for the
trouble.  Can't beat that.
Steve
