I had a Cruising Design on my Catalina 27, and it worked fine except when you really needed it to work (winds building, way overpowered). At those times it would get caught up after rolling in 1/2 way, requiring someone to go up on a pitching foredeck to unstick.
My E39 has an older Harken model (at least 15 years old), that works perfectly in all weather.
