FWIW, the average PHRF numbers for the CS36 and Merlin (deep keel) are 123 and 126 respectively. So quicker than either the Catalina 34 or Jenneau 34.2.
I have chartered this boat. I was very impressed with the way she sails. Just set the lines in steady wind and go cook lunch. She'll be at the same point of sail when you return.
