Storm protection in Quincy Bay

Safe Harbor Marina Bay in Quincy Bay, seven miles south of Boston, Massachusetts, now benefits from an SF Marina floating concrete breakwater system.

Marina Bay’s west basin has a long history of recurring storm damage and the new breakwater is engineered to overcome extreme weather events. It not only protects the marina’s floating timber docks and fingers from the area’s numerous seasonal storms, but also reduces costly repairs.

Steel-reinforced and virtually unsinkable, each of the 14 Type-400 SF Marina pontoons used in the project has a buoyancy rating of approximately 102.4 psf yet offers exceptional stability. An exclusive coupling system absorbs and distributes stress loads. The pontoons are anchored on 30in (76cm) steel piles.
Designed in an L shape, the attenuator is 722ft (220m) long x 13ft (4m) wide on the west basin. Doubling as docking space for transient megayachts, it has electric and water supplies routed through integrated utility ducts. A second smaller section extends from the marina’s rubble mound breakwater to overlap the larger portion and protect the harbour mouth. Each of the 21 pontoons is secured with a pair of 30in (76cm) steel piles.
Whether cruising the Boston skyline, fishing for flounder or exploring the many small islands in the area, both local and visiting boat owners find Safe Harbor Marina Bay ideally situated. It can accommodate vessels with drafts up to 12ft (3.6m) and up to 150ft (46m) long without beam restrictions. The marina hosts four restaurants and a short stroll along the Nantucket-style boardwalk provides access to an extensive range of shoreside amenities and community-centric activities.
