Delaware · 14–20 m
Mr. G and the Rusty Pusher are two small tug/pusher-type vessels reefed on Delaware Artificial Reef Site #10, which lies 5.5 nautical miles from Indian River Inlet in 55-66 ft of water. The site's wrecks and barges are heavily encrusted with blue mussels that attract sea bass, tautog and triggerfish, making it a regular stop for Delmarva dive and spearfishing charters.
Delaware · 14–20 m
YC-725 was a 251-ft, 2,344-ton steel vessel built in 1918 at Globe Shipbuilding in Superior, Wisconsin (originally the Contoocook, later Elda) and finished her career as a U.S. Navy open lighter barge. She was sunk in 1946 and lies on what is now Delaware Artificial Reef Site #10 in about 60 ft of water, 5.5 nautical miles from Indian River Inlet, where her mussel-covered hull holds sea bass and tautog.
Delaware · 14–20 m
YON-80 is a 110 x 35 ft, 400-ton U.S. Navy yard fuel-oil barge built in 1941 by Dravo Corp of Wilmington, Delaware, and sunk as reef material on Delaware Artificial Reef Site #10 on March 10, 2010. The barge sits in the site's 55-65 ft depth range, 5.5 nautical miles off Indian River Inlet, encrusted in blue mussels and holding sea bass and tautog.
Delaware · Up to 12.8 m
Artificial reef built from Concrete, Plus 35' and 42' Steel Vessels (“P3” and “Dolphin”)
Delaware · 12.2–15.2 m
The broken remains of an unidentified late-19th-century wooden sailing ship (often attributed to the 1880 barkentine D.H. Bills) lying at the mouth of Delaware Bay roughly 12 miles off Cape Henlopen. The low rubble mound, about 100 ft long and 6-8 ft high in 45-50 ft of water, still yields fragments and occasionally intact pieces of its Victorian-era English china cargo. It is one of the region's classic artifact dives but must be timed to slack tide because bay currents rip across the flat sand bottom.
Delaware · 31–40 m
The Atlantic Mist was a 185-ft, 640-ton WWII Patrol Craft Escort (PCE-880) later converted to a menhaden fishing boat, sunk as reef material on the tri-state DelJerseyLand artificial reef about 26 nautical miles from Indian River Inlet. The reef site bottoms out at 121-131 ft, making this an advanced cold-water wreck dive shared by Delaware, New Jersey and Maryland divers alongside the destroyer USS Arthur W. Radford.
Delaware · 31–40 m
The Gregory Poole was a WWII Admirable-class minesweeper (AM-215) later converted to a menhaden fishing vessel, sunk on the tri-state DelJerseyLand artificial reef roughly 26 nautical miles from Indian River Inlet. The wreck rests on a 121-131 ft bottom near the reef's other vessels, including the destroyer USS Arthur W. Radford, and is a staple advanced wreck dive for Delaware, Maryland and New Jersey charters.
Delaware · 14.6–24.4 m
A British-built freighter that sank in 1942 after colliding with the tanker Voco at the end of the Harbor of Refuge breakwater off Cape Henlopen, then was wire-dragged and demolished as a navigation hazard. The wreck today is a sprawling field of twisted plates and machinery on sand in roughly 50-80 ft of water that shelters lobster, tautog and sea bass. Its position at the bay mouth means strong currents, and local charters dive it at slack tide.
Delaware · 1.5–18.3 m
The mile-and-a-half-long outer breakwater off Cape Henlopen, built of more than a million tons of granite in the early 1900s to shelter the mouth of Delaware Bay. The submerged rock slope is heavily encrusted with mussels and attracts tautog, sheepshead, striped bass and record-class black drum, making it the region's storied freediving and scuba spearfishing site; the Gypsum Prince wreck lies at its seaward end. Depths along the wall run from the surface rocks down to about 40-70 ft on the surrounding bottom, with strong tidal flow around the structure.
Delaware · 24–30 m
Redbird Reef is Delaware's best-known artificial reef, 16.5 nautical miles off the coast, built from more than 700 retired New York City 'Redbird' subway cars plus 86 military vehicles, eight tugboats and barges and thousands of tons of ballasted material. The structures sit in roughly 80-110 ft of water and are completely encrusted with cold-water corals, frilled anemones and mussels, with sea bass, tautog and flounder swimming through the car windows. The Chesapeake Cruiser record marks one of the reefed workboats on the site.
