The Alaunia is a wreck site located off Selsey, United Kingdom. Divers encounter an overhead environment that requires strict buoyancy control to prevent silt disturbance, which can reduce visibility to one metre. The site reaches a depth of thirty-two metres, necessitating careful monitoring of depth gauges. Entanglement risks are present, and divers should carry line cutters. Water temperatures fluctuate between 9 and 18 degrees Celsius, requiring appropriate exposure protection. As this is an open-water marine environment, divers may encounter various temperate reef fish and invertebrates typical of the South Coast of England. Divers should arrive self-sufficient as facilities are not confirmed at this location.

Gascogny is a wreck dive located off the coast of Selsey, United Kingdom, suitable for intermediate divers. The site reaches depths between 22 and 30 metres, with an average depth of 25 metres. Access is by boat only. Divers should expect variable visibility ranging from 5 to 7 metres, necessitating the use of a dive light. Water temperatures fluctuate between 9 and 18 degrees Celsius throughout the year. Due to the nature of the wreck structure, divers must maintain buoyancy control to avoid entanglement. Conditions, including current and visibility, can shift significantly, so local checks are recommended before diving.

The Axwell is a wreck site located off the coast of Selsey, suitable only for advanced divers due to its depth and challenging conditions. The wreck lies at depths reaching 45 metres. Divers must contend with strong, unpredictable currents and visibility that fluctuates significantly between 1 and 20 metres. Access is by boat only, and the site requires careful planning around slack water to ensure a manageable dive. Given the depth and potential for entanglement within the wreck structure, this site demands high levels of experience. Water temperatures range from 9°C to 18°C, making a drysuit the recommended choice for year-round diving.

The Oceana is a wreck site located 4000 metres offshore, functioning as an artificial reef. Divers can explore the structure at depths ranging from 10 to 30 metres, with an average depth of 25 metres. Access is by boat only, and the site is suited for intermediate divers due to moderate currents and potential entanglement hazards. Visibility typically ranges between 5 and 15 metres. Water temperatures fluctuate from 9C in winter to 18C in late summer, necessitating a drysuit or thick wetsuit. Divers should plan their visit around slack water and carry a surface marker buoy for boat recovery.

Dresden is a shore-entry reef site located in Selsey, United Kingdom. It offers shallow, calm conditions suitable for newly qualified divers to practice buoyancy and navigation. Water temperatures fluctuate between 9C and 18C throughout the year, requiring appropriate exposure protection. Visibility at this coastal reef is variable, and divers should monitor current strength during entry and exit. As facilities are not confirmed, visitors must arrive self-sufficient with all necessary equipment, including a surface marker buoy. Maintain awareness of your surroundings while in the water, as sharks have been reported in this area. Always check local visibility reports before travelling, as conditions can shift considerably between visits.

Wittering is a shore-accessible site on the South Coast of England, offering a combination of reef and wreck diving. Divers typically explore depths between 5 and 10 metres, with an average depth of 7 metres. The site is suited for intermediate divers due to moderate currents and potential surf at the shore break. Visibility varies significantly from 2 to 10 metres, influenced by local weather conditions. Hazards include entanglement risks, rip currents, and strong tidal flows. Divers should consult tidal tables and consider timing entries around slack water. Facilities including parking, air fills, equipment rental, and guided tours are available to support local diving activities.

HMS Pine is a wreck site located 9000 metres off the coast of Selsey, United Kingdom. Resting on a flat seabed at depths between 15 and 19 metres, the wreck provides significant hard relief. Divers should expect moderate currents and variable visibility ranging from 5 to 10 metres, occasionally dropping to two metres. Due to the risk of entanglement, divers must carry a cutting tool and a surface marker buoy. This site is suitable for intermediate divers, with boat access required. Planning dives around slack water is essential to manage current conditions effectively.

HMS Ariadne is a wreck and artificial reef located off the South Coast of England. The site lies at depths between 14 and 30 metres, with an average depth of 20 metres. Access is by boat only, approximately 8 kilometres from the shore. Divers encounter mild currents and visibility ranging from 5 to 15 metres. The wreck features overhead sections and potential entanglement hazards, requiring intermediate skill levels and careful buoyancy control. The structure supports a variety of temperate marine life and invertebrates typical of the region. Guided tours are available and recommended for those unfamiliar with the wreck layout to assist with navigation.
