Help! I bought a 1976 Catalina 22 on it's original trailer. I believe it is a Trailrite of the same year. It's license plate is gone and I don't lnow where to look for the VIN number. The boat has clear title and, as I said, is on it's original trailer, so I'm sure the lost title is can be verified and replaced. I just don't know how or where to start.
