Is the CAT the only RV ferry out of Maine?

Answer 1

Maine Ferries has a website.
There is another ferry from Bar Harbor to Yarmouth, NS I think it is called the Scotia Prince, and it takes overnight to make the trip from Maine to NS. The Cat does it in about 3 hours.
We took the Cat going to NS, then a slow ferry from Digby NS to St John, then drove back into Maine.
Don't forget now you will need a passport for the trip into Canada.
