The Zane Gray is an artificial reef and wreck site located off Cape Hatteras. Divers typically explore the structure at depths ranging from 12 to 20 metres, with an average depth of 16 metres. Access is by boat only. The wreck features an overhead environment that necessitates wreck certification for entry. Conditions include mild currents, though surges and swells can occur, and visibility generally ranges from 10 to 20 metres. Water temperatures fluctuate significantly between 10 and 23 degrees Celsius, often with a thermocline present. Divers should remain vigilant for boat traffic, strong currents, and cold water temperatures when planning their dives.

The U-701 is a German Type VIIC U-boat resting upright on a sandy bottom at a depth of 37 metres. Located 37 kilometres offshore, this site requires boat access and is reserved for advanced divers due to the depth and strong currents. Visibility is highly variable, ranging from 3 to 30 metres, and thermoclines may occur. Divers should plan for a 30-minute bottom time and coordinate descents with the turn of the current. The hull serves as an artificial reef, supporting a variety of reef fish and invertebrates. Given the offshore location and potential for shifting conditions, divers must carry a surface marker buoy and manage gas supplies carefully.

The Irving H is a wreck site located 10.5 kilometres off Cape Hatteras, United States. Resting at depths between 65 and 70 metres, this site is intended for intermediate technical divers. Access is by boat only. Divers should anticipate visibility ranging from 5 to 10 metres and manage potential hazards including boat traffic, entanglement risks, and variable currents. Given the depth, bottom times are typically limited to 40 minutes. Divers must conduct thorough team briefings and establish clear turn-pressures before descent. Local charter operators should be consulted for current conditions and seasonal patterns prior to planning a dive.

Oregon Inlet Reef, located off Cape Hatteras, offers an intermediate dive experience at depths between 5 and 20 metres. Access is strictly by boat, with divers typically spending 40 minutes exploring the site. Visibility ranges from 5 to 10 metres, and mild currents generally assist with navigation. Divers should remain aware of potential surge and swell conditions, as well as heavy boat traffic in the area, particularly during ascent. Water temperatures fluctuate significantly throughout the year, ranging from 10C in winter to 23C in summer, necessitating appropriate thermal protection for the season. Always confirm sea conditions and boat availability with local operators before planning a trip.

Dionysus is an artificial reef located 10.5 kilometres off the coast of Cape Hatteras, United States. This wreck sits at a consistent depth of 20 metres and requires boat access. Divers should expect mild currents, though conditions can vary, and visibility typically ranges between 5 and 10 metres. The site is suitable for intermediate divers who must remain vigilant regarding entanglement risks on the wreckage and significant boat traffic during ascent. Water temperatures fluctuate seasonally from 10C to 22C. The structure supports a variety of reef fish and invertebrates typical of the region. A surface marker buoy and a cutting tool are recommended for all dives at this location.

The USCG HU-25 Falcon 2111 is a decommissioned Coast Guard aircraft deliberately sunk as an artificial reef off the coast of Cape Hatteras. Resting at a consistent depth of 8 metres, the wreck provides a compact structure for divers. Visibility typically ranges from 5 to 10 metres. The site is accessible only by boat and is suited for intermediate divers due to potential hazards, including boat traffic, entanglement risks within the airframe, and variable currents. Water temperatures fluctuate significantly throughout the year, ranging from 8 to 25 degrees Celsius. Divers should monitor for currents before entry and deploy a surface marker buoy during ascent.

The Buoy is an artificial reef and wreck site located 12875 metres off the coast of Cape Hatteras. The structure sits at depths between 20 and 30 metres, with an average depth of 24 metres. Divers experience visibility ranging from 10 to 20 metres and mild currents. Due to the depth and the presence of an overhead environment, this site is suited for intermediate divers. Hazards include potential surge, entanglement risks, and the need for careful management of nitrogen narcosis and decompression limits. Divers should avoid entering the wreck or swim-throughs unless specifically trained for technical diving. Boat access is required to reach this location.

The U-1105 is a World War II German Type VIIC/41 submarine resting in 8 to 30 metres of water off the coast of the United States. This artificial reef offers intermediate divers a wreck with notable structural integrity. Access is exclusively by boat, with the site located 15 kilometres from shore. Divers should be prepared for variable conditions, including surface surge, mild to strong currents, and visibility ranging from 10 to 20 metres. Due to the depth and potential for entanglement, careful buoyancy control and surface marker buoy use are essential. The site is suitable for intermediate divers, with typical dives lasting around 40 minutes.
