[C38] How to approach an argument with a sailor

I guess the source of the data would be important, is it from a GPS, knot
meter or ????

Advice seeking time.

So, I've got a friend who sails on a VERY fast boat. A very winning boat.
Probably one of the fastest in San Francisco. It's crewed by a bunch of
amazing sailors including some Cup guys. However, she's not really a sailor
and I've had to explain things like what a knot is vs mph. The boat is a
Santa Cruz 37 rates in a 27PHRF. Now, she claims and has some text messages
from other crew saying they've hit 26knots in the bay. I call BS. I pull out
all my math on hull speed, plain force calculations on what it would take to
make that boat go into full plane. 
I've tried showing what PHRF means and that a 27 means they only average
1/2 knot faster than the J/105's. I've tried pulling out their race times
and showing they're only averaging about 6-7knots during races. . 
This does not matter.

  Probably most of us have seen exceedences in hull speed for our boats
going down waves and whatnot. However, that's not the claim. The claim is
they REGULARLY go 16-20 knots in bay races. This is 2x or more their hull
speed. .

Thoughts on how to explain this or anyone have experience with a SC37?

Anders
