Before you arrive
Access notes
The older attribution to a Q-ship engagement near Ushant was superseded and concerns UC-36. The reviewed specialist record supports identification, but no reliable current measured depth is asserted here. This record documents a wreck and its research history. It does not establish public charter availability or permission to visit. Confirm access with the responsible authorities and qualified local support; respect the site’s naval-heritage context.
Plan within your training
Conditions and hazards
Offshore weather and currents, depth and decompression exposure where applicable, low or changing visibility, entanglement, unstable or damaged metal and possible ordnance. Do not disturb remains or remove objects.
Independent resource notice
This record is a starting point for independent verification. Access, closures, moorings, weather, currents, depth, visibility, operator availability, and site conditions can change without notice. Confirm current information with the responsible operator, property owner, managing authority, or another qualified local source before planning or attempting a dive.
