Simplified Wreck Survey
The Jakob Maersk is a broken tanker wreck and underwater obstruction located near Leixões, Portugal, at coordinates 41 10.2 N, 8 42.09 W. Following an engine room explosion in 1975, the vessel settled by its stern on rocks near the Leixões South Mole. The wreck consists of several broken sections, including a bow section resting on the rocks south of Leixões Harbour and a stern section. Although the funnel was once visible above the water, it has since disappeared beneath the surface. This sunken tanker remains an underwater obstruction with depths recorded between 8.2 and 8.7 meters in the coastal waters near the Leixões approach channel.
