P29
A Cold War minesweeper. A Maltese patrol boat. Now a 52-metre military wreck.
The P29 feels less like a single wreck feature and more like a journey along an entire ship - stern, superstructure, gun deck and bow unfolding one after another.
Resting upright on the sand off Ċirkewwa, the P29 is a 52-metre former Kondor I-class minesweeper and patrol vessel. Its long, narrow profile gives the dive a different rhythm from a compact tug, with the hull, bridge and open deck guiding the route from end to end.
The seabed sits at roughly 34 metres, while the upper structure is substantially shallower. That allows several profiles - a deeper full-hull circuit, a shallower superstructure tour, or penetration for properly trained wreck divers.

From the Baltic to the Maltese seabed.
Before becoming a dive site, the P29 had already changed countries, roles and pennant numbers - beginning as an East German minesweeper before ending its working life patrolling Maltese waters.
Boltenhagen
Built at Peenewerft in Wolgast, East Germany, the vessel entered service as Boltenhagen, hull number GS09. She was the eighteenth Kondor I-class minesweeper built and also carried out patrol duties along the East-West German border.
German Coast Guard
After German reunification, Boltenhagen moved into Federal Coast Guard service as BG31. Her weapons were removed and equipment changed before she was finally decommissioned in 1996.
P29
Malta purchased the vessel in 1997 and renamed her P29. She served with the Maritime Squadron of the Armed Forces of Malta, carrying out coastal patrols, border-control work and anti-smuggling operations.
The scuttling
After decommissioning, the ship was cleaned and prepared as a diving attraction. On 14 August 2007 she was deliberately sunk off Ċirkewwa, settling upright on the sandy seabed as an artificial reef.
Fifty-two metres of ship, laid out in a straight line.
The P29 rests upright on its keel. The long hull, open superstructure and military deck fittings make orientation unusually intuitive from the outside - once you know which end is which.
Openings into the machinery spaces
The stern is often the first section reached from shore. Large preparation openings expose the former engine-room area and provide dramatic sight-lines through the hull without requiring entry.
Bridge, wheelhouse and long corridors
The superstructure breaks up the otherwise long, low profile of the ship. Doorways, windows and internal rooms make this the most complex part of the wreck and the section where good buoyancy matters most.
The military silhouette
The forward deck and gun position give the P29 its most recognisable profile. Pulling away from the bow reveals the full length of the hull behind it - one of the wreck's classic wide-angle views.
A patrol boat becoming a reef
Nearly two decades underwater have turned the cleaned steel into habitat. Open decks attract schooling fish while shaded recesses shelter ambush predators and invertebrates.
Choose how much ship you actually need.
The P29 can be dived as a complete exterior circuit, a shallower upper-structure tour or a trained penetration dive. Depth and gas usually decide more than ambition does.
Classic P29 circuit
The best first dive for understanding the entire ship.
- Enter from Ċirkewwa and navigate towards the wreck using the agreed compass bearing, seasonal buoy and local landmarks.
- Approach the stern and use the first minutes to establish orientation before dropping towards the deeper hull.
- Follow one side towards the bow, pausing at the superstructure and gun deck rather than zig-zagging across the wreck.
- Pull away from the bow for the full silhouette, then return along the opposite side at a gradually shallower depth.
- Finish over the upper structure and leave enough gas and no-decompression margin for the swim back to the reef and exit.
Upper-structure profile
More time around the bridge, less time on the sand.
- Reach the wreck and remain above the main deck rather than descending immediately to the keel.
- Work around the bridge, wheelhouse and upper deck, using the open windows and doorways for views through the ship.
- Visit the forward gun position and bow from above instead of dropping to the seabed for a low-angle view.
- Return over the superstructure, maintaining a progressively shallower profile before leaving the wreck.
- Use the extra margin for a controlled return along the reef rather than spending it extending the bottom phase.
Penetration plan
Open preparation holes can make an overhead environment look deceptively simple.
- Agree the exact penetration before entering the water - including entry, exit, maximum depth, gas limits and who leads.
- Use only sections appropriate to the team's wreck training, equipment and familiarity with the current structure.
- Maintain a continuous exit strategy and avoid passing restrictions, entanglement hazards or unstable metal simply because an opening exists.
- Control finning and buoyancy to avoid disturbing silt or contacting surfaces where scorpionfish and other marine life may be resting.
- Exit with enough reserve to complete the deep-water ascent and the offshore return without relying on the wreck's buoy line.

The P29 is long enough that the dive develops as you move - approach, stern, superstructure, gun deck, bow - instead of presenting the whole wreck at once.
The ship emerges from the blue
The swim offshore creates a proper reveal. At first there is only open water, sand and seagrass; then the upper structure appears and the long hull begins to stretch away beneath it.
Because the P29 sits upright, orientation is immediate once the deck comes into view. The challenge is not understanding the wreck - it is deciding how much of it to spend time on.
The gun deck changes the character of the wreck
The forward gun position gives the P29 a silhouette that no ordinary workboat can imitate. It is an obvious photographic landmark and a reminder that this ship once had an entirely different purpose.
Move away from the bow and the full 52-metre hull becomes visible behind it - one of the moments when the scale of the wreck is easiest to appreciate.
Openings everywhere, shortcuts nowhere
The bridge, wheelhouse and prepared openings make the midships section visually busy. Light passes through doors and windows, often allowing divers to look through rooms without entering them.
That openness is part of what makes the wreck attractive, but it can also make penetration look easier than it is. The ship remains a deep overhead environment once you cross inside.
The wreck gets bigger as your time gets smaller
A full exterior circuit can feel generous at the start. By the time the bow, stern and superstructure have all competed for attention, the available bottom time suddenly feels much shorter.
The best finish is usually upward rather than outward - returning across the higher structure before leaving the wreck and beginning the swim back towards the reef.
