CO monitor, batteries and breeching?

I went ot SONFLOWER on her mooring today. I was greeted with a beep beep sound. The CO detector had flat batteries. the first job of the day was change them. That way they would not get so flat while we were off the boat that teh beep beep beep stopped and we would be in danger of not knwowing especially withthe state of my meory at the moment.

I started the engine and charged the batteries. The engine was a little reluctant and I might invest in a can of "easistart" for when the weather is really cold.

I chatted to a couple of other moorers: there is little news except that it is reproted that below Banbury lock the three mile pound has little water in it! Considering the amount of water that was flowing through the lock paddles over the weekend this is very surprising. We are wondering whether there has been a breech or culvert collapse.

I also spoke to Sue, nb "No Problem",  who is waiting for work at Tooley's Boatyard before heading for Gloucester or some other beauty spot. She was disturbed by the news above as she certainly needs to turn round to head north. She is therefore toying with backing to Tooleys. We know that is very possible.
