[C320-list] Hull speed

[McCullough, Kirk]

I have made 7.3 on the knot meter once or twice in idea conditions, flat
water, off the wind and not surfing. This is within the margin of error
of the knot meter as compared to the theoretical hull speed. I'm sure 9
kts is not possible.

Without gps you don't know your sog - speed over ground - what are you
using to measure "over 9 knots"?
(Doubt your speed)

Hull speed is 1.34 X sq root of waterline length...which comes out to
7.1.  
As for speed thru the water or gps speed, I get over 9 knots (thru  the
water) 
on a reach, don't have a gps so ground speed is not available.
