Watch a ship's final voyage, then dive the wreck. 29,782 UK and Irish wrecks, offline, with animated Final Voyages.
29,782 wrecks in UK and Irish waters, from UK Hydrographic Office records.
Depths, survey history, seabed conditions and legal protection status, and
the database works with no signal.
WreckAtlas is for anyone with an interest in shipwrecks: divers, historians,
and the merely curious. It carries the detail that decides whether a site is
worth the boat time, and the history behind the ships that are gone.
THE RECORD
Each wreck record contains the hydrographic information held for that site.
For most sites this includes:
- Least depth and seabed depth, shown as a range, because a least-depth
figure on its own flatters a dive
- How proud the wreck stands, and the orientation of the hull on a compass
rose
- Seabed composition and scour dimensions
- Dated survey history with the surveyor named
- Tonnage, dimensions, year lost and vessel type
- The chart classification the hydrographic office gives the site, in plain
English rather than jargon
11,105 records also carry an account of how the wreck was lost, drawn from
the hydrographic record: the circumstances, the ship's earlier
history, and what became of her afterwards.
RESEARCHED HISTORIES
Separately, over 100 notable ships carry a full written history, researched and
checked against published sources, not generated. HMS Hampshire and Lord
Kitchener. The Scapa Flow German fleet. The Lusitania. The Mendi. The
blockade runner Iona II. What happened, where she lies now, and what you
will find on the site.
FIND WRECKS NEAR YOU
Nearby sorts wrecks by distance from your position, from one kilometre out
to fifty. Select one to see its bearing in true and magnetic, the distance,
and the wreck's own axis on the dial so you know which way the hull lies.
All calculated on the device, so it works offshore with no signal.
GPS accuracy varies at sea. Treat positions and bearings as reference, and
use proper navigation equipment.
WAR GRAVES AND PROTECTED SITES
Many wrecks in these waters are legally protected, and the restrictions differ. A Controlled Site under the Protection of Military Remains Act cannot be dived without a licence. A Protected Place can be visited on a look but don't touch basis. Wrecks designated under the Protection of Wrecks Act generally require a licence to dive, while scheduled monuments and Irish National Monuments protections have their own rules.
WreckAtlas identifies which designation applies and summarises the restrictions, rather than flagging everything as "protected" and leaving you to find out.
DISCOVER
Eleven curated dive regions, from Scapa Flow to the Manacles. Notable wrecks grouped by warship, submarine, ocean liner and war grave. And eight Final Voyages, animated accounts of famous last passages, from departure to loss.
YOUR DIVE LOG
Log a dive against the wreck itself, with depth, duration, visibility, a rating and photographs.
Your log syncs through your own private iCloud storage, so it survives a new phone. WreckAtlas has no access to your dive records.
FREE, NOT A TRIAL
Every record, every history, every survey entry. No paywall, no account, no trial, no advertising. Free, and it stays free.
WHAT THIS APP IS NOT
Not a navigation aid, and not certified for navigation. It does not plan dives, assess qualifications or judge conditions. UKHO positions can be wrong or superseded, and identifications are sometimes provisional. Verify on site, dive within your training, and treat the app as a starting point rather than an authority.
THE DATA
Wreck records are UK Hydrographic Office data, © Crown copyright and database right, used under the Open Government Licence v3.0. Heritage designations come from Historic England, Historic Environment Scotland, Cadw and the Northern Ireland Department for Communities. The written histories are our own research and are not UKHO material.

- A Skip button on every Final Voyage takes you to the end.
- Fixed the Go to Wreck button, which was sending you back to the Discover menu.
- New researched wreck histories, including the Tayleur, the Tuscania, the Koln at Scapa Flow and the Somali on the Farne Islands.
- Side scan sonar images of the Cragside, Enecuri and Countess of Erne wrecks off Portland, kindly provided by a user.
