Maine Marina Installs New Floating Concrete Dock

Spring Point Marina is located on picturesque Casco Bay, a popular boating destination in Maine. Once a shipyard for Liberty Ships, the South Portland recreational harbor recently upgraded its facility with the construction of a state-of-the-art floating concrete dock and walkway from SF Marina. The new section adds 1,150 feet of straight transient dock space to the marina.
Installed by Rockland, Maine-based Prock Marine Company, the Spring Point Marina project included seven 65.5-foot-long by 17-foot-wide floating concrete pontoons. The new dock’s wave-attenuating design helps shelter the existing docks and slips from waves and large wakes from passing boats. The dock sections, built to withstand the nor’easters common in the area, are highly buoyant and virtually unsinkable. They are moored on internal 24-inch steel piles to provide extra stability.

The contractor routed utilities, including 50-amp and 100-amp power, water and other services through the dock’s internal ducts. A slightly narrower floating concrete was used for the walkway.

The construction of the docks went very smoothly because the SF Marina pontoons were easy to put together, according to Mike Soucy, Port Harbor Marine director of operations. Spring Point Marina is one of five employee-owned Port Harbor Marine properties.

Spring Point Marina has over 275 slips and can accommodate yachts up to 200 feet in length. A full-service boatyard, it has a 50-ton Travelift, 10-ton forklift, hydraulic trailers and the capacity to handle any repair.
