I was going to say that Alex or Jeff would be along shortly, but Alex beat me to it.
Alex, I get error messages on all the sites. Is it me?
I was looking this up the other day. I know that the theoretical hull speed on my C34 is in the mid to high 7's. I also know that I have surfed it at much higher speeds. I need to do a little more looking and I know that your references will probably give me some answers.
