Massachusetts Marina Completes New Floating Breakwaters and Docks

SF Marina Systems completed a dock construction project for the Macmillan Pier Commercial Marina in Provincetown, Massachusetts.

The marina had sustained extensive damage during several storms over the past several years. With funding from the Federal Emergency Management Agency (FEMA) covering part of the cost, the city was able to replace the marina and add critical floating breakwaters to protect and enhance the facility.

SF Marina built nine sections of floating breakwater, each 14 feet wide by 65 feet long. The attenuator, almost 600 feet long, is moored on 36-inch long steel piles; these 18 piles hold the structure in place and resist the force of the waves. Nine solid cast-concrete floating docks replaced the marina’s old docks.

All of the marina components were delivered via barge and unloaded by crane. ACK Marine Contracting of Quincy, Massachusetts, completed the installation in the fall of 2019.

The new marina will support more than 40 commercial fishing vessels, which use the facility as a homeport for fishing the waters off Cape Cod. The benefits of the new breakwater/attenuator were noticed almost immediately during some fall gales in the area, according to SF Marina Systems.
