Yes, you'll be rafted at the public marina on the North side of the island. You most likely will be rafted with a bunch of absolute drunks who will bang and stumble all over your boat with little regard to the damage you do. You quite possibly will be tied next to some maniac with a $500 Thompson cuddy. They run the dope-sniffing dogs on the docks and board & search boats so be forewarned. Arresting drunks and guys with open containers is the primary revenue producers for the city so be aware of that too. They fill the town with ferries-full of amateur hour kids who want to drink themselves into oblivion.
You can also get dockage at a private marina to the west- a better choice.
If I were you, I'd pay a visit to PIB but I'd hang at Kelley's Island. In an Ohio context, PIB is Panama City on Spring break, Kelley's is Key West.
