BoatWiki - Databases
TitleCheck is a product of Auto Data Direct (ADD), a long time provider of state registration information for vehicles. Although vehicle oriented, their reports also include boats for those states that integrate vehicle and vessel records into the same database.
There is a free preliminary search available by entering a boat hull identification number in place of that for vehicles. If there is a positive hit, you will be able to download the respective report at a minimal fee. Keep in mind that you will not find ownership names and addresses in any of these online state level searches.
