The Trent and Mersey Canal is a single width canal west of Burton-on-Trent, but it is a double width canal for the rest of its length. All the locks we’ve done since rejoining the boat have been twice as wide as we need, significantly longer, and mostly very deep too. This means that each lock takes a lot more time and effort to deal with. If we find another narrowboat going the same way as us, we should be able to share the locks, and so also share the water and the effort. We’ve only managed to do that once – as it happens in the only hydraulically powered, keeper operated lock on this section.
