For anyone interested, BBC's Radio 5 Live will have a programme this evening at 21:00 GMT on the recent loss of the Swanland.
They will show how Swanland has had a history of deficiencies etc, and evidence from a former captain who says the ship was often badly loaded, causing the middle to sag and then spring back up again when unloaded.
It should be possible to listen to the programme at:
