I just found out while trying to register my 1965 Old Town WC canoe that Ohio now requires that boats without a 12 digit HIN (hull inspection number) be assigned one before they can be licensed. The original original serial numbers are not sufficient. This means calling and setting up an appointment with a license bureau that handles watercraft, taking the boat to their location and getting it physically inspected. For me that's about an hour drive away. If you want a small Alternative Registration sticker and the boat previously had the Traditional Registration stamps with gigantic ugly numbers, that requires an extra step of having the bureau call in to ODNR Watercraft while you're at their location to make the switch.
