Local dive-centre listing for the wreck site.
Boat-reached artificial wreck off Whitsand Bay.
Boat-reached artificial wreck off Whitsand Bay.
HMS Scylla is an intentionally sunk former Royal Navy frigate in Whitsand Bay off Cornwall, reached by boat from Plymouth and dived as an exterior scenic wreck. The wreck sits in open water with tide-aware planning, variable visibility, and a strong overhead-risk profile if divers approach the interior, which is now considered unsafe to penetrate.
Conservative baseline from public research. No community dives logged yet.
Depth range, seasonality, and planning context.
Reported Depth
9m - 26m
Depth Note
The wreck tops out around 9 m and sits on a seabed around 21-26 m depending on tide; public site guides emphasize the wreck profile and tide planning rather than one fixed dive depth.
Best Season
Late summer to early autumn, when sea temperature and visibility are usually best.
Typical Conditions
Open-water wreck diving with tidal planning, variable visibility, and a busy boat-dive scene in season.
Hazards, restrictions, and access requirements.
Key Hazards
Safety Notes
Treat the wreck as an overhead environment. The site manager advises no routine penetration because the interior is heavily congested and collapse-prone.
Access Restrictions
Boat access only, with no routine wreck penetration and no artifact removal.
Legal Notes
The site manager says artifacts are not to be salvaged and the interior should not be entered without specialized training and a planned exercise.
Community notes to help plan your visit.
Scuba Diving
Scuba is the intended use case here: a boat-reached artificial wreck with exterior exploration, photography, and training opportunities.
Freediving
Not a freedive site; the wreck is offshore and shaped for scuba, not breath-hold use.
Snorkeling
Not a snorkel site; it is an offshore wreck dive reached by boat.
