[C320-list] Hull speed

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.
