Great topic! Unfortunately, I am not happy...lol, y'all have "real" HIN's. Try going to your state wildlife office and asking for a title and registration for a 70/71 Glastron Carlson CV-16 that has HIN 2410.B! The first thing the wildlife offer said, "that's not a hull ID number"...so I presented her with pics of the Hull ID plate! I received the title 10 days later..titled as 2410.B....Gregg might share the link to more about this boat.
