Reserve your slip today!

Atlantis Marina has everything you’re looking for in a marina and more, including great location, marine services, helpful staff, a thriving boating community, and competitive pricing. Whether you have a large or small boat, are new to boating or are a veteran seafarer or liveaboard our marina will accommodate you and our friendly community of boaters will welcome you. Located in the sheltered waters of Winthrop harbor your boat will be equidistant from Boston’s inner harbor or the open ocean. Onsite marine services provide the convenience and quality of service we’re known for. Our boating community is a diverse group of sailors, leisure boaters, and anglers and even year round liveaboards who liven up the docks and are happy to “grab a line”. Compare our rates to other Boston Harbor marinas and you’ll see why our community is constantly growing and why we’re continually expanding.

    Dock extension and new steel pilings
    In November we added 600 feet of docks secured by 16” steel pilings. Boston Marine Engineering was here with their massive barge mounted crane adding 200 feet of dock to B, C, and D docks. This will give us an additional 45 deep water slips.
