By 5.15 I was in the car and heading for London. Amazingly, it turned out that a colleague knows Tony and Julie from Muchgigglin, with whom we had such a good time sharing the locks on Friday. He's even due to see them in London this week.
I got back to the marina at about 4.30 this afternoon, and put a coat of varnish on the cabin porthole liners. Since I've been back, there's been a series of squally showers and it's turned really cold.
