P29

Also known as: Boltenhagen, Maltese patrol boat P29

A former East German patrol boat scuttled off Cirkewwa in 2007, its cut-open interior and mock deck gun paired with the nearby Rozi tug.

The dive

A mock deck gun juts from the bow of P29, fitted there deliberately so divers have something to photograph before they've even reached the rest of the wreck. From Susie's Pool, the swim out passes a memorial stone on the sand and an old anchor sitting in seagrass, both landmarks before the hull itself resolves out of the blue. The deepest sections, the sand-level hull and the interior passages, are the usual first stop, worked before no-decompression time runs down, with divers then climbing back up through the superstructure via one of several entry points cut specifically for penetration. Groupers and scorpionfish sit close to the plating, barely moving. Moray eels work the crevices, and barracuda pass overhead in the open water above the deck.

What makes it special

P29 reads less like a wreck that happened to become a dive site and more like one built for the purpose. The cut interior access points, the fitted gun, the memorial stone and anchor placed as underwater waypoints: all of it points to a site designed around diver experience rather than left as found. Divers who've done both describe her as larger and generally sitting deeper than her neighbour Rozi, and where that tug is known for fish, P29 is known for structure, a bigger silhouette to explore with more interior to work through. The pairing with Rozi, a second wreck 140 metres away from the same shore entry, is what turns a single dive into Cirkewwa's signature circuit.

History and origin

Long before Cirkewwa, this hull spent the Cold War as Boltenhagen, an East German Kondor I-class minesweeper built in 1969-70 to patrol the border rivers between East and West Germany. German reunification brought her into the Federal Coast Guard for several more years of service, guns dismantled and equipment modernised, until she was decommissioned in 1996. Then came Malta. She was bought the following year, renamed her P29, and put her to work with the Armed Forces of Malta's Offshore Command on anti-smuggling and border-control patrols until 2004. The Malta Tourism Authority acquired her in 2005 specifically to create a new dive attraction, and on 14 August 2007 she was scuttled off Cirkewwa, her Cold War service now three careers and half a continent behind her.

Know before you go

Plan gas and time for the deeper sections first: the dive begins deep and stays deep, so no-decompression time on air runs down quickly and bottom-time management matters. A primary torch is worth having for the cut interior routes, and a dive computer is standard given the depth. The entry points make the interior look inviting, but treat it as guided territory, not a solo penetration. The wreck carries a no-take policy, so leave any artefacts or souvenirs where you find them. The surface swim from Susie's Pool runs 150-200 metres. Pace yourself, and arrive at the wreck with air and energy left to spare, not already spent. If you're combining P29 with Rozi, work out your gas plan for both wrecks before entering the water.

Why Dive P29

What makes this dive site stand out.

  1. Ex-East German minesweeper

    A Kondor I-class vessel before Malta bought and scuttled her in 2007

  2. Mock deck gun

    A non-functional gun fitted at the bow for divers to photograph

  3. Paired with Rozi

    140m away on the same Cirkewwa shore entry, dived as one trip

  4. Cut-open interior

    Multiple entry points let divers explore wheelhouse, bridge and engine room

AdvancedMin cert: Open WaterNitrox recommended

Open Water divers can join a supervised dive on the upper hull and exterior from about 12-20m; it isn't an independent dive at that level. The full profile to the sand-level hull (34-38m) is commonly marketed as AOWD, though PADI's own 30m Open Water Diver limit falls short of that depth, putting it in the Deep Diver 30-40m band, and Malta's independent-diving rule also requires certification to at least 30m before diving unguided. Interior penetration calls for Wreck Diver training, with Deep Diver and Nitrox strongly recommended given the depth.

Summary

The deep sand-level sections (34-38m) sit at the edge of recreational no-decompression diving on air, and interior penetration adds route-planning demands for trained divers. The shallower upper hull (12-20m) is more approachable under supervision.

Safety considerations

What can go wrong here, and what divers do about it. Conditions change - take the briefing from the operator on the day.

  • Overhead: Some interior passages are tight, suitable only for experienced or trained divers.Carry a primary torch and stick to routes you've briefed with a guide.
  • Depth: The dive begins deep and stays deep, so no-decompression time on air runs down quickly at the sand-level sections.Plan nitrox or a shorter bottom time, and track your no-decompression limit closely.
  • Surface and boat traffic: The shore entry involves a longer surface swim, roughly 150-200m, to reach the wreck.Pace yourself on the swim out so you still have air and energy for the dive itself.

Frequently Asked Questions

How deep is the P29 wreck?▾

The highest point of the structure sits around 12m. The hull on the sand sits at roughly 34-35m, with depths to 38m reported at the bow. Most of the interior and superstructure exploration happens in the 20-34m band.

What was P29 before it became a dive site?▾

She started life as an East German Kondor I-class minesweeper named Boltenhagen, built in 1969-70 for Cold War border-river patrol. After German reunification she served the Federal Coast Guard, then Malta bought her in 1997 for border-control duties before retiring her and scuttling her off Cirkewwa in 2007.

Can P29 and Rozi be dived together?▾

Yes, and most divers treat it as one outing rather than two separate trips. The wrecks sit about 140 metres apart off the same shore entry, so plan at least an hour combined, whether that's a surface interval between two dives or one extended profile.

What certification do I need for P29?▾

Open Water divers can join a supervised dive on the upper hull and exterior, about 12-20m; it isn't an independent dive at that level. The full profile to the sand-level hull (34-38m) is commonly marketed as AOWD, though it actually sits in the Deep Diver 30-40m band, and interior penetration calls for Wreck Diver training on top of that.

What will I see at P29?▾

Groupers, damselfish, scorpionfish and moray eels are the wreck's most consistently reported sightings, with bearded fireworms and nudibranchs also on the structure and barracuda passing overhead. Cuttlefish move through in spring to spawn.

How do I get to P29 from shore?▾

Enter at Susie's Pool at Cirkewwa and swim roughly 150-200 metres out, following a surface marker buoy in summer if one's in place. A memorial stone and an old anchor in the seagrass serve as underwater landmarks before the hull comes into view.
