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.

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.

Frode is a shore-entry reef dive located in Selsey on the South Coast of England. This site offers a manageable environment for divers, featuring shallow and generally calm water. As a shore-based location, it is accessible without a boat, though divers should arrive self-sufficient as facilities are not confirmed. Conditions at the site are variable, with both visibility and currents subject to change; checking local forecasts before heading out is recommended. Water temperatures fluctuate between 9 and 18 degrees Celsius throughout the year, necessitating the use of a well-fitting wetsuit for thermal protection.

The Indiana is a shallow wreck located off the coast of Brighton and Eastbourne, resting at depths between 8 and 12 metres. This site serves as an artificial reef, providing a hard-substrate habitat suitable for temperate marine life. With mild currents and an average depth of 10 metres, it is an accessible choice for beginner divers. Access is strictly by boat, as the wreck lies approximately 1609 metres from the shore. Divers should be aware of low visibility, which typically ranges from 5 to 10 metres, and remain alert for boat traffic during surface ascents. Monitor depth gauges closely, as the seabed drops to 21 metres in the immediate vicinity.

Barn Hill is a shore-entry reef site located on the South Coast of England. The site features shallow water, providing a suitable environment for newly certified divers to practice skills. Visibility is variable, reflecting typical conditions for inshore reef sites in this region. Water temperatures range from 9 to 18 degrees Celsius throughout the year, necessitating a thick wetsuit or drysuit, particularly during winter months. Divers should exercise caution regarding the surf and shore break during entry and be mindful of jellyfish in the water column. Avoid contact with sharp rocks on the seabed. Check local conditions and facility availability before planning a dive.

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.

The City of London is a wreck dive located off the coast of Brighton and Eastbourne, resting at depths between 18 and 23 metres. This shore-accessible site is suited for advanced divers due to moderate currents and the potential for variable visibility. Divers should be prepared for low-light conditions and carry both primary and backup torches. The structure presents a risk of entanglement, making a wreck reel and cutting tool essential equipment. Water temperatures fluctuate between 9C and 18C throughout the year. Divers should consult local operators regarding visibility reports before planning a dive, as conditions can change rapidly.

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.
