Re PY 23 - I have sailed past lots of them. Paceship made a fixed keel 23' that is a good boat but the PY 23 is a keel/centerboard and pretty slow. That said they were well built and very good looking - just more of a motor sailor than sailboat from what I have seen. I have even passed one while I was sailing (Catalina 27) and he was motoring with a 9.9 HP outboard just screaming. The sailing qualities do not impress me at all. But they are pretty!
Not sure we're talking about the same boat. There was a Paceship 23 in our club a number of years ago and I always thought it was a nice looking boat. Similar to the ODays and Catalinas of the same era. It rates PHRF 246, versus a Cat 22 at 270 and a Cat 25 at 228, so pretty competitive.
