According to the news report - she's lying in 280 feet of water, approximately 11 miles east of Collieston. Read somewhere that it was possibly initially discovered when BP was surveying for the Forties pipeline. More details here: The Type VIIC boat U-1206 - German U-boats of WWII - uboat.net
Differing reports as to the number of men on board (possibly as many as 50) which at the time took to liferafts after the submarine's batteries were immersed in seawater - giving off chlorine gas forcing it to the surface. Four drowned at Boddam (near Peterhead), after one of the inflatable liferafts capsized.
This is an extract from Jim Burke (Buchan Divers) who led the dive: "All four torpedo doors were open and a single warhead was spotted in one of the port-side tubes. Apparently, she fired off torpedoes before she sank at least one was heard to have exploded at the end of its run."
The last of four rubber liferafts were also visible, still in its holding bay. The only major damage appears to be to the anti-aircraft guns and periscopes which have been accidentally trawled off the wreck by passing fishing boats. The main conning tower remains intact. Mr Burke said: We have dived on so many locations looking for this U-boat. There were times in the past when we were absolutely sure we had found her, but it turned out not to be. This time though, we had new information about where she had gone down and we were confident this was the right site.
During their search, the divers came across several wrecks, including the Windward Ho steam trawler which sank in 1917 three miles off Peterhead.
