Eaton's Boatyard Marina

Eaton's Boatyard sits right on Sea Street in the heart of historic Castine, a small Maine peninsula town with Revolutionary War forts, a maritime academy, and some genuinely good waterfront dining within easy walking distance. The yard offers moorings and handles marine services, making it a solid base if you're cruising Penobscot Bay. Vessel capacity runs up to 200 feet, so there's room whether you're in a modest sailboat or something considerably more serious.
