Automatically checked
No recent diver reports from the past 14 days

A report that passes the automatic checks will appear here with the dive date, diver’s display name, and temperatures at each depth.

Reports are automatically checked for plausible dates, depths, and temperatures. They are observations, not forecasts; confirm conditions before diving.

Depth readings

Why divers know this place

Highlights

Inverted battleship hull, propellers, exposed main guns, blast deformation and marine growth.

Before you arrive

Access notes

Technical certification, decompression planning and deep-wreck experience are required. Inverted structure is an overhead; no penetration without suitable training and guide approval. No boat relationship is inferred.

Plan within your training

Conditions and hazards

Mandatory decompression, inverted overhead, entanglement, sharp/unstable metal, possible ordnance, sharks and extreme remoteness. Do not handle artifacts.

At the site

Facilities and support

Technical liveaboard and decompression support; shore-based emergency resources are extremely limited.

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.
