Overnight, the battery voltage had dropped to 10.5. Set out from Gailey at 9, but by the time we got to Hatherton (?40 minutes) it was only up to 10.6. Decided to turn around, go back to Gailey and ring engineering, since it was was possible they might do a home visit. John confirmed it was an alternator problem, because it was 10.6 even while the engine was running. Allan on NB Pengalanty was moored near, and recommended Oxley Marine. They sent Philip, who replaced the regulator on the domestic alternator. He also took away the fire door to complete the repair to the glass-holding-screw holes.
Ran down from Gailey to just short of Autherley junction – a beautiful spring evening. Didn't meet any boats coming the other way, and there was very little earlier.
Total distance: 14 miles, 0 locks. 5.5 hours engine time.
