HMS Scylla is a decommissioned Royal Navy frigate deliberately sunk in 2004 to serve as an artificial reef. Located 1500 metres off the coast of Selsey, the wreck sits upright on a sandy seabed at depths of 32 to 34 metres. This site is suitable for intermediate divers and requires boat access. The structure is largely intact, providing penetration opportunities through internal sections. Divers should be prepared for an overhead environment, variable visibility between 5 and 15 metres, and mild currents that can strengthen unpredictably. Due to the depth and potential for entanglement, proper buoyancy control and the use of a torch are essential.

HMS Prince Leopold is a wreck dive located 9656 metres off the coast of Selsey, United Kingdom. Resting at depths between 27 and 30 metres, the site is suited for intermediate divers. The wreck features penetrable sections and various swim-throughs. Visibility typically ranges from 5 to 10 metres with mild currents. Due to the depth and potential for entanglement, divers should carry a cutting tool and maintain awareness of their surroundings. The site is accessible only by boat.

Arrive self-sufficient as local facilities are unconfirmed.

Edenwood in Selsey offers a combination of natural and artificial reef structures, providing a varied environment for divers. The site is shallow, with depths ranging from 5 to 10 metres, allowing for extended bottom times. Shore entry is standard, and the mild currents make this location suitable for beginners building their confidence. Visibility is highly variable, ranging from 1 to 20 metres depending on local conditions. Divers should exercise caution regarding sharp coral and rocks during entry and while navigating the reef. Water temperatures fluctuate between 9 and 19 degrees Celsius throughout the year, necessitating appropriate thermal protection such as a drysuit or thick wetsuit during cooler months.

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.

Bembridge Lifeboat Slip is a shore-entry snorkel site located in Selsey, United Kingdom. The site is characterised by an old outfall pipe and pier structures that have become encrusted with marine growth. Snorkellers can explore these artificial features alongside nearby eelgrass beds, which serve as a nursery area. Water temperatures at this location vary between 9C and 19C throughout the year. Due to the nature of the environment and the required navigation around structures, this site is best suited for intermediate-level snorkellers. It offers a unique opportunity to observe the development of marine life on submerged man-made infrastructure.

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.

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.
