The sections of the U boat were cut through with a diamond wire system (I believe that was used on the salvage of the Russian Kursk too.) It is amazing the way it has cut cut along pipes etc.

Some more shots of the Resurgam. A model would be interesting - fore and aft stability would be interesting. ( A problem with all early submarine types it seems.)
