We had been trying to get certain parts of our navigation system working for about three years. The Raymarine dealer turned up in the morning. He spent some time pondering over the fluxgate compass before replacing it. But we were unable to calibrate it on the canal, so he had to set it roughly, manually, and wait for us to reach a wide river for a proper calibration. He took the chart plotter away for an extended bench test. We had another long cruise in the sunshine, finishing for the evening at Halte La Falotte, a short way downstream of Villeton. This spot advertises free mooring and a mineral museum. At thought we should give it a first try, so went up the steep steps at 18:40, leaving Christine to finish making dinner and promising to return in about 20 minutes when it was due to close. The lady that runs the museum (with her husband) was extremely passionate about her collection of rocks, shells and fossils and was intent on explaining every last detail about each cabinet. At 20:00 we made our excuses and left. Dinner was ready, but definitely needed re-heating.
