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.

AR-140 is an artificial reef and wreck site located 15.2 kilometres off the coast of Cape Hatteras. The site features a wide depth range, extending from 4 metres down to 40 metres, with an average depth of 38 metres. Divers encounter mild currents, though surge and swell are common. Visibility typically ranges between 5 and 10 metres. Due to the depth and potential for entanglement, this site is suited for intermediate divers. Water temperatures fluctuate significantly between 7C and 21C, requiring appropriate thermal protection. Divers should remain vigilant for boat traffic, lionfish, and entanglement hazards while exploring the structure.

AR-130 Buoy is a shallow artificial reef located off the coast of Cape Hatteras, United States. Situated at a depth of 4 metres, this site is suitable for beginner divers looking to practice buoyancy and observation. The site is accessible only by boat and features mild currents. Visibility typically ranges between 5 and 10 metres. Water temperatures fluctuate significantly throughout the year, ranging from 7 to 26 degrees Celsius. Due to the presence of boat traffic in the area, divers must maintain awareness during ascents and are required to deploy a surface marker buoy to remain visible to vessel operators.
