[C320-list] Hull speed

[Jerry Brown]

At the end of last season on Lake Ontario we were wing on wing with a single 
reefed, full batten, main and a 150 Genoa unreefed and saw 9.4 knots surfing 
for extended periods, dropping to 8.5 off the surf  in 35knots of wind. 
That lasted for about 20 mins when  we had to close reach and the speed 
dropped with a half furled genoa to about 8.5 knots.  The Wing on Wing was 
exciting but only really possible because the wind was absolutely steady and 
even then a couple of time I wondered who was in charge.......
