Scotties on the River
I like Scotties, although I haven’t been often enough. They used to have slips available for boats. That was a great idea, but apparently not enough boats used them.
Chattanooga being a “river town,” with a long history of travel by boat, one might think there would be more restaurants with their own dock. The one establishment you would absolutely think would have a dock is the Boathouse, a fine place to dine, but you will need to arrive by road or Riverwalk, not the water.
Of course, is one docks at Ross’s Landing, there are many restaurants within walking distance. I believe you can tie up in the area near the pier for up to four hours (or perhaps longer if no one notices) for free. Staying overnight is going to require paying Erwin Marine (who manage the docks) for a reservation through the Dockwa app or website.
And if you want to eat on the water, you can always do a dinner cruise on the Southern Belle.
