El Boreas wreck

The boat ride from Port Marina runs roughly five minutes. You drop down a line into open blue, and within a dozen metres the silhouette of a tugboat resolves below: deck at 22 m, wheelhouse already visible above, propeller waiting at 32 m. Most centres run the same loop in the same order. Bow first, then aft along the deck to the propeller for the depth check, then back up to the hold (the air pocket is pointed out, not entered as a swim-through), the engine room with its resident congers, the kitchen, the captain's cabin with the bathtub still bolted in, and finally up to the bridge before the line. Forty metres of hull, slightly heeled to port, encrusted in sponges and bryozoans, with red gorgonians on shaded surfaces. The interior is what people come back for, and the briefing leans on small groups and good buoyancy because the engine room silts out fast on a sandy bottom. Boreas reads as a circuit, not a wall.

Three things separate Boreas from the rest of the Palamós wall and pinnacle dives. The penetrable interior, with five rooms cleared of hazards before scuttling, is the local rite of passage that many in Catalan diving forums describe from their first deep dive after Advanced. The compact depth band keeps the entire vessel in one no-deco-friendly window for a recreational AOW diver running a single dive. And the backstory carries weight that other Costa Brava sites simply do not have: a 1930s German Navy tugboat, post-war Atlantic crossings, a hashish seizure off Begur, and a deliberate scuttle in 1989. Few sites in this stretch of coast ask a diver to navigate inside a structure on a planned route, and even fewer hand them a complete history to think about while they do it.

The vessel began as Pellworm, a deep-sea tugboat launched in the 1930s for the German Navy and assigned to submarine school work. It survived the war, passed through American hands, returned to German service, and eventually entered civilian work under a Panamanian flag, picking up the name Boreas around 1980. In 1989 Spanish customs intercepted the ship off the coast of Begur with a hold full of hashish (community accounts cite roughly 500 kg) and seized it. After the hull was decontaminated and loose hazards removed, the vessel was deliberately scuttled off Palamós on 23 January 1989 to create an artificial reef. It has held that role for more than three decades, colonised by sponges, bryozoans, and gorgonians, with congers settled into the engine room.

Boreas earns its advanced rating from the prop, not the deck. The 32 m bend is where the no-deco window tightens, and the engine room is where buoyancy mistakes turn into a silt-out. A computer is essential, and nitrox is worth taking when a centre offers it. Bring a torch and a backup for the interior, plus a line cutter or knife for the loose pipes and cables on a 35-year-old hull. Carry an SMB; the wreck sits in a busy navigation corridor and surfacing in open water is not an option here. On summer weekends, agree on the ascent line with your buddy and centre before you splash, because several boats often share the wreck and ascending on someone else's line is the most-mentioned downside in local trip reports. Five Palamós centres rotate boats over the wreck week in, week out: Palamós Dive Center, Gidive, H2O Diving Center, Anemone Diving, and Fosca Divers.
