JORN – Bettolina

This small Dutch motor vessel, originally launched under the name Gretha, later became known as Jorn after joining the First German Transport Flotilla in November 1943.

On 12 February 1944, she met her end off the Bay of Silence in Sestri Levante, struck by fire from a British P-47 D Thunderbolt during a World War II air raid. Today, her well-preserved wreck offers an evocative window into wartime history and a dive rich in marine life.

Dive Highlights

The descent line brings you down to midship, where the wreck sits upright in navigation position at a depth of around 30 metres. Between the two cargo holds lies a small raised platform, once home to an anti-aircraft machine gun—now only ammunition remnants remain as evidence of her armament.

The bow is remarkably intact, though a large breach on the port side marks the impact that ultimately led to her sinking.

Moving aft, the engine room and galley still contain original tools and kitchen utensils, making this a particularly immersive wreck for history enthusiasts. On the starboard stern, you’ll find a river-style anchor, while the propeller and rudder are clearly visible, lying neatly on the muddy seabed.

Marine Life & Photography

The wreck is not only a historical gem but also a vibrant habitat for marine life. The aft ladder glows with clusters of jewel anemones (Corynactis viridis), and the bow hosts elegant spirographs, swaying in the current.

Within the nooks and crannies of the wreck, divers frequently encounter conger eels, moray eels, octopuses, spiny lobsters, and lobsters. For macro lovers, there’s no shortage of anemones and colourful nudibranchs. Pelagic visitors like amberjack and snapper often sweep in from the blue, hunting schools of anchovies and damselfish.
