About this site
U-1021 is a German U-boat wreck lying off the Cornwall coast in the western approaches, an area of seabed that holds a number of submarines lost during the Second World War. The site is rated a technical dive, consistent with the depths and conditions typical of U-boat wrecks in this stretch of water. It draws technical wreck divers who work this part of the English Channel approaches specifically to explore these submerged hulls.
