At the next lock we caught up with another boat. The crew were clearly enjoying themselves, but not very experienced. They only had one crew member working the locks, and she had got confused by meeting a boat coming the other way, and now having us joining them too. I arrived at the lock just as she was starting to open the top paddle with the bottom gate still open and Clare trying to drive in. I shouted to her not to. She realised her mistake and went to shut the gate instead. Once things had calmed a bit, I apologised for introducing myself by shouting – I think she accepted it. We worked the remaining three locks together, including an aborted attempt at a simultaneous lock entry.
