Lookup by Vermont State ID Number

Growing up we had family that came to visit us in Vermont where we would spend significant time boating and fishing on a small aluminum boat that my uncle had. Well, he recently passed and I would like to find the current owner of the vessel, if it's even still out there, to try to purchase it back from them if at all possible. Everything that I have seen online says that I need a hull ID to find what I'm looking for, but literally all I have is the name of my uncle who owned it and an old picture that shows the state ID number. Help!!!
