Located conveniently just off the west end of the Cape Cod Canal, Safe Harbor Onset Bay is the perfect location to pause and refresh before continuing your journey north or south—or as your base to explore Buzzards Bay and the Elizabeth Islands. Friendly, helpful staff. Dockmaster Roland is a treasure! Modern, clean and well-maintained facilities with an old-time feeling you won’t find at the big marinas with concrete docks and golf carts. Whether you are looking for a place to sit out the storm or take in the charms of the South Coast, Onset Bay Marina has everything you need.
