The Clyde is 100-150 metres wide where they are using it, which is
comparable with the Thames at Battersea.

There must be places in London where some of these could run - and if they
had a few unused at the weekend, they might be able to run Jubilee Line
replacement services in East London, which they can't at the moment. But I
don't know if the slipways are in the appropriate places.
