I know this has been talked about before, but on my registration, my hull number is strange. WSZ160190689. Doesn't seem to conform to any of the Catalina hull numbers. The registration says it's a 1972. I'm guessing it's not correct, but I can't find any markings on the hull (in the usual places) to verify. It's definitely an older Catalina. Has the slide-out galley and the old-style front hatch, the pop-top, swing keel, etc. From all the Catalina 22s I've seen, it's definitely one. Just trying to figure out the hull number discrepancy.
