Another boat had arrived so he readied the lock again for them, hoping rerunning might also reset any electrical programming tizz it may have got into. The narrow boater got out and chatted. He understood the concern and in solidarity said he wouldn’t leave till we had got our key back. Another boat was approaching and we waved it in too. I walked on the bridge as giving it a bounce sometimes works, but still once the boats had left the lock, the bridge didn’t shift. Shane and the other guy were discussing the predicament, they could hear a click but it didn’t seem to release the catch holding the bridge open. I went to the bar for swinging the bridge and gave it a small push in each direction, a wee shoogle, then returned to the release handle and lifted and this time it did lift and release and the bridge was free to be swung back in place. Shane and the other chap swung it over and our keys were free at last. The friendly local chap promised to do the next bridge for us, which was in sight. They duly did and called to us as we went through some advice on mooring possibilities in Goole. He wasn’t going there but was a regular.
