The Atlantic Reefmaker Story

Dave Walter, of Walter Marine, developed the Reefmaker concept. He used the concept on three projects: Deadman’s Island (2011/2012 – 200 feet, 2013 – 50 feet, and 2015 – 1,050 feet), Yellow River Aquatic Preserve (2013 – 1,000 feet) and Shark Island Demonstration project (2015 – 500 feet).

In 2014, Randy Boyd began working with Dave Walter to provide an engineering perspective for the Reefmaker product. Randy saw a show featuring the Reefmaker and became convinced the concept would work as a wave attenuation system to stabilize coastal shorelines along the Cape Fear River for the Brunswick Town/Fort Anderson project he was working on at the time.

In 2016, Randy became a staff engineer for Atlantic Reefmaker. Since his involvement in the Reefmaker concept, Randy has been involved in the development and implementation of Bonner Bridge Sub-merged Aquatic Vegetation (SAV) Mitigation, Brunswick Town/Fort Anderson Phase I, and Brunswick Town/ Fort Anderson Phase II projects. Work is beginning on Brunswick Town/Fort Anderson Phase III and will be completed in 2021.


After just five years the Atlantic Reefmaker’s positive impact is seen in critical projects along the North Carolina coast. The Reefmaker structure has helped mitigate shoreline erosion by reducing wave energy and reviving rich ecosystems around and near the shore’s edge, including salt marshes and sea grass. Atlantic Reefmaker’s unique design provides an ideal aquatic habitat and cover for fish, oysters, crabs and mussels. The shore’s edge is critical to the broader coastal ecosystems that thrive in shallow water, abundant sunlight, plentiful terrestrial and marine nutrients, tidal and wave flushing environments, and a wide range of habitat types.

The permeability of the Atlantic Reefmaker structure can be custom designed to promote flushing through the structure for marsh restoration or reduced to near-zero porosity for sediment capture.

The Atlantic Reefmaker’s foundation creates a footprint whose adverse environmental impact is significantly less than traditional rock sills.
