Simplified Wreck Survey
The German U-boat U-778 lies at coordinates 55 32.484 N, 07 28.772 W, off the coast of County Donegal, Ireland, in the North Atlantic Ocean. Originally scuttled during Operation Deadlight following World War II, the wreck is a significant maritime heritage site. Hydrographic surveys describe the U-778 as an intact submarine resting on the seabed at a general depth of 67 meters. The wreck measures approximately 54 meters in length, 5 meters in width, and 4 meters in height, lying on an orientation of 135/315 degrees. Latest bathymetric data confirms a least depth of 60.63 meters over the obstruction. The vessel is reported as being partially buried but remains a identifiable submarine wreck. The site is monitored by the UK Hydrographic Office and Geological Survey Ireland, documenting the historical preservation of this U-boat at this specific deep-water location.
