Before you arrive

Access notes

McCartney gives a 65 m hydrographic depth and documents characteristic UB II bow tubes. This is a deep technical wreck requiring current local planning. 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.
