Many thanks Ron! Interesting stuff

How does the owner/manager bit work out? Is the manager effectively who buys and pays for the ship and then they would rent/lease her out to the shipping company?

Also was there a typical way of scuttling with explosives that might be possible to tie in to any evidence on the wreck or was it just a case of slapping a load of explosives somewhere below the waterline and get off sharpish?!
