No experience firsthand sailing, however I agree- beautiful boat and seems to be well built. Solid glass hull, great lines. All of the drawbacks and hinderances of a 60's designed boat of that size however. Where is the one you found?
the MKII version is a Bermuda 40 lookalike. looks like they have deep drafts which could be a problem. the pilot berths behind the settee really restrict interior space. make sure it has a diesel. they have a lot of exterior teakmaintenance
some of the best times of my life were spent on a boat. it just took a long time to realize it.
There is a member here who had one, and maybe still does. Check the Social Groups "Plastic Classics." I'll check, if I find him I'll post it. Beautiful boats. Like most CCA boats, they get more waterline when they heel... and they love to heel
