P29

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. Scorpionfish sit still against the plating. Moray eels work the crevices, and barracuda pass overhead in the open water above the deck.

P29 reads less like a wreck that happened to become a dive site and more like one built for the purpose. This wreck feels built, not found. The entry points cut for penetration, 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. She's larger and generally sits 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.

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.

Plan gas and time for the deeper sections first, since 34-38m leaves only around 14 minutes of no-decompression time on air. 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 surface swim from Susie's Pool runs 150-200 metres. Pace yourself. Arrive at the wreck with air and energy still in reserve, not already spent. If you're combining P29 with Rozi, work out your gas plan for both wrecks before entering the water.
