What is the formula for hull speed?  Square root of length at water line
divided by something?

That's as fast as displacement boat will go

Paul:  
    Fast with sailboats is relative. The C38 is lots faster than the C34,
which means that in a mile and decent wind, the C38 can go about 50 yds
farther than a C34. I am sceptical of the claim for any 38' cruising
monohull of "8-9 knots consistently in moderate winds." Discreet Charm, C38
#50, will do 7.5 to windward (GPS) in 18-20 knts wind, no currents, under a
110% jib. Same wind on a beam reach gives 8 to 9 kts, on a good day. We have
clocked 15 kts downwind in 25 kts wind with our asymm spinnaker.  These were
white knuckle experiences, crazy, and scary; we aren't racing people.
Spinnaker on a pole with several skilled crew would probably do better. 
    Listen to the racers for max speeds.
Regards, Don
