The UK Hydrographic Office wreck database on your phone — depths, seabed relief, wreck axis, dated survey history and war grave designations. The notable ships carry a curated history too. Every record, every history, your position and the bearing to the wreck all work with no signal; only the map tiles need one.
0–20m · Shallow
Every charted wreck in UK and Irish waters, clustered so the map stays readable and coloured by the band you'd plan a dive around. Pinch in and the counts break apart into individual sites.
Search by name, filter by depth, era, vessel type, war grave status or region. The database is bundled inside the app, so the map draws the same whether you're at your desk or on the deck.
20–35m · Sport
The hydrographic detail that decides whether a site is worth the boat time: least depth against seabed depth, how proud the wreck stands, the orientation of the hull, and a survey history with the date and the surveyor attached to every entry.
Depths show as a range where the seabed sits well below the shallowest point, because a least-depth figure on its own has a habit of flattering a dive. War grave designations sit at the top of the record, not three taps down.
Beyond the survey figures, 10,087 wrecks carry an account of how they were lost — the circumstances, the ship's earlier history and what became of her afterwards, parsed out of the hydrographic record.
50m · Advanced
The notable wrecks carry a written history: the ship, the voyage, how she was lost, and what is left of her on the seabed today. Researched over months, and checked against the sources.
About this wreck Curated
Cunard liner built in 1893 by Fairfield Shipbuilding at Govan, of 12,950 gross tons, and a Blue Riband holder on the Atlantic run. Sold for scrap in 1914, she was bought instead by the Admiralty and converted into one of the world's first aircraft carriers, with a flying-off deck built forward over her bow and a hangar for seaplanes. She pioneered techniques for launching aircraft from a moving ship, though she missed Jutland after failing to receive the signal to sail with the Grand Fleet.HMS Campania · UKHO 2825 · Firth of Forth
War graves, warships, submarines, ocean liners, the historical oddities, and the popular dives every hard boat runs to. Plus dive regions from Scapa Flow to the Sound of Mull, each with conditions and a season.
50m · Advanced
Nearby sorts every wreck by distance from where you are, from one kilometre out to fifty. Tap one and the compass takes over: the bearing in true and magnetic, the distance counting down, the wreck's own axis drawn on the dial so you know which way the hull lies before you drop.
Come within fifty metres and it tells you you're over the site. Position, bearing and distance are all worked out on the device — no signal, no data, nothing to fail when you're an hour offshore.
50m+ · Technical
Final Voyages traces a ship's last crossing over the chart — the departure, the warnings that went unheeded, the position of the attack, and the moment she went down. Narrative cards surface as the track advances, so the story unfolds at the pace the voyage did.
Voyages built so far include Lusitania, Leinster, Royal Charter, Mendi, Association, Royal Oak and Hampshire.

Seabed
Log a dive straight from the wreck you were on and it carries the site with it. Depth, bottom time and a rating, totted up into a running count of dives, wrecks and deepest dive.
Your dive log syncs to your own iCloud, so it survives a new phone or a reinstall — and it stays yours. It goes to Apple, not to us; we have no way of reading it.
Alongside it: your kit list, your favourites, and a guide to UK and Irish training routes for divers working towards wrecks.

WreckAtlas is a reference tool. It is not certified for navigation and must not be used in place of official charts, publications or a properly maintained plotter.
Hydrographic records contain errors. Positions drift, depths are recorded to differing datums, and some entries have not been surveyed in fifty years. Verify on site.
Designated war graves and protected wreck sites carry legal restrictions. A licence may be required. The designation flag in the app is a prompt to check, not a clearance.
Dive within your qualifications, your currency and your plan. Nothing in the app assesses whether a site is appropriate for you.
