Dive into History
If you can provide any information on these boats that would be great, as this page simply cannot be completed without the help of people who have personally dived on these boats. Each boat will have its own page here, hopefully with some charts and photographs, additionally the pages will have some contact information for those interested in diving these boats. I will only list diving operators who show these sites proper respect, especially the war graves.
U-85, U-352, U-701, U-853, U-869 / U-Who, U-1105 and U-2513.
The Kattegat is the body of sea between Denmark and Sweden. Dive sites there include U-251.
At least the U-711 is a dive site with a few more possible locations including;
U-320 and U-1053.
Ireland & Northen Ireland
There are probably more dive sites than these two.
