Re: Strange Catalina 22??
Not sure if this thread is dead or not, but I'd like to second David's comment about the benefit of using a plate versus a sail stop:
"It allows you to get the main closer to the boom while furling/reefing, which is nice."
My boat is similar to a C22 and I have helped friends shake down their C22s fitted with sail stops. Flaking their mains at the end of the day is a pain compared to what I'm used to. My main flakes entirely on the boom which is nice.
Go with the plate - they can't be that expensive!
