Sixteen Fathom Artificial Reef
16-Fathom Artificial Reef
13 nautical miles southwest of Fire Island Inlet, 1.33 sq miles
Depth: 85 to 103 feet
This is a new reef for 2023, 1-nm square. This reef is located in the separation zone of the very busy Ambrose-Nantucket shipping lane. I can't believe that was permitted by the ACOE.
So far just concrete blocks and forms, no vessels.


All manner of concrete, steel, and stone rubble from dredging, demolition projects, and other construction is used as artificial reef materials. This material is generally available at very low cost or free from construction companies who are more than happy to get rid of it. Transportation costs determine where this material is used by the Reef Program.

This Rustic Ferry is Getting Dismantled in Queens to Become an Artificial Reef
The Prudence Ferry has been abandoned for years, but will get a second life in the waters off Fire Island this summer.
The City, News Partner
Mon, Apr 20, 2026

By Lilly Sabella, The City
Behind the gate of a waterfront restaurant, a rusted ferry wobbles on the waves of the East River. It’s become a familiar eyesore for residents of Long Island City, Queens since it was first moored to the Anable Basin in 2012 and has floated there since, a forgotten lump of metal - until now. The abandoned ferry, named Prudence, is getting a second life as an artificial reef. Each Saturday morning this spring, residents in masks and safety goggles leap from stable ground onto the ferry to remove any hazardous materials and make it fit for sea creatures to move in.
