I recently was given an old Sunfish by a friend. He has no paperwork anymore. We think it is a 1976 because it has a 1977 NJ registration sticker and it fits the description of that era (metal gun'l, etc.) Per the Sunfish Age and Hull Identification resource of this website" Hull Identification NumberIf there is a serial number molded into the hull, it will be in the upper right corner of the transom. It can be deciphered to give you the manufacturer and model year." I've looked all along the transom and across the deck at the stern as well and see no hull id. What am I missing? I should have a hull number to get a launch permit in Pennsylvania.
