I thought Cablebandit took a ferry from Bar Harbor to Yarmouth, is that still running or is the Portland to Yarmouth ferry replacing it? The Bar Harbor ferry isn't a CAT and it would be an overnight trip. Is the CAT quicker? I remember the old CAT when we took a 1 week hiking trip in Acadia years ago and was told it was a 4 hour trip to Yarmouth from Bar Harbor.
Regardless, I'm happy to see more options!
