Sadly, ships are a scarce sight today on the Clyde, and it’s the same on the Tyne, birthplace of the Mauretania, the Ark Royal and those colossal supertankers, and both rivers are fighting to keep their shipbuilding history alive. I took a boat trip down the Clyde to the modern Braeside Shopping Centre. It was half an hour before I saw a ship being built, and then it was a navy vessel, one of two being built where once the river would have been full of ships. The work on the Tyne was similarly scant, and again, navy vessels. No liners, no supertankers, not even a dredger. I rang Swan Hunter last week to tell the men I interviewed when the programme was being broadcast: the union shop steward Micky Blench told me only one of the was still working there, and he wasn’t expecting to be there much longer. Their gallows humour had come true. Now there is nothing.
