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.

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.

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.

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.

Arno is a shore-entry reef site located in Selsey, United Kingdom. The site features a wall with depths ranging from 20 to 30 metres. Divers should be aware of moderate to strong currents present at the wall. Visibility at this location is variable and can shift between visits, so checking local conditions prior to entry is essential. Water temperatures fluctuate between 9C and 19C throughout the year, requiring appropriate thermal protection. As facilities are not confirmed at this site, divers should arrive fully prepared with necessary equipment, including a surface marker buoy and surface cover.

Britsum is a wreck and reef site located 1500 metres off the coast of Selsey. Divers encounter depths ranging from 20 to 40 metres, with an average depth of 30 metres. Access is by boat only, and the site features moderate currents that require careful planning around slack water. Visibility typically fluctuates between 3 and 10 metres. Due to the depth and the nature of the wreck structure, this site is suited for intermediate divers. Hazards include entanglement risks, sharp surfaces, and low visibility. A drysuit is recommended given the water temperature range of 9 to 19 degrees Celsius.

Cuckoo is a wreck site located 500 metres off the coast of Selsey, United Kingdom. This marine site sits at depths between 12 and 15 metres and requires boat access. Divers should anticipate moderate currents that can strengthen, necessitating careful planning around slack water. Visibility is variable, ranging from 3 to 10 metres. Due to the wreck structure, entanglement is a primary hazard, and divers are advised to carry cutting tools. Water temperatures fluctuate between 9 and 18 degrees Celsius throughout the year. The site is suited for intermediate divers who can manage buoyancy and navigation in changing conditions. The surrounding habitat supports various temperate marine life and invertebrates.

The Far Mulberry is a prefabricated concrete caisson from the D-Day landings, resting on the seabed at a depth of 10 to 12 metres. Functioning as an artificial reef, the structure offers sheltered recesses and hard surfaces that support temperate reef fish and invertebrates. This site is accessible only by boat, located approximately 1609 metres from the shore. Divers encounter mild currents and visibility ranging from 5 to 15 metres. Given the water temperatures of 9 to 18 degrees Celsius, adequate thermal protection is required. The site is suitable for beginners, though caution is advised around the concrete edges of the caisson to avoid sharp surfaces.
