The Atlantic Reefmaker Story

Dave Walter, of Walter Marine, developed the Reefmaker concept. The Reefmaker/Walter Marine deployed its first artificial reef in 1986. Today they are the largest reef builders in the United States with over 50,000 reefs deployed. All he artificial reefs feature his patented design of natural reef like material. These artificial reefs provide a habitat for all forms of marine life, from juveniles to adults. The reefs are durable enough to withstand hurricane 5 force winds and waves. These limestone reefs can be created in any size, including the largest available in the US. There are four divisions of reefs: fishing reefs, snorkeling reefs, wave attenuators (to help mitigate shoreline erosion), and ships. 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 a number of shoreline erosion mitigation projects including, Bonner Bridge Sub-merged Aquatic Vegetation (SAV) Mitigation, Atlantic Harbor, and Brunswick Town/Fort Anderson Phase 1, 2 and 3A . Work is beginning on Brunswick Town/Fort Anderson Phase 3B and projected to be completed in late 2021.


After just five years the Atlantic Reefmaker’s positive impact is seen in critical projects along the North Carolina coast helping to mitigate shoreline erosion. Atlantic Reefmaker’s unique design reduces wave energy, reviving rich ecosystems around and near the shore’s edge, including salt marshes and sea grass. This provides an ideal aquatic habitat and cover for fish, oysters, crabs and mussels, because 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, Thereby making the Atlantic Reefmaker one of the best choices for shoreline erosion mitigation.
