Yes, I remember it -- unfortunately, I don't have a copy. It was a very good ecological drama about a Father (played by Bill Nighy, now a huge actor in this country and abroad) and his daughter living on a boat. As I recall, the plot had something to do with this mad old lady (a very scary actress called Judy Parfitt) and some kind of device which was a little like a sundial. It was very good. It was shown at the start of 1993 (one of the first childrens productions made by new franchise-holders Meridian, I believe) and repeated the following year.
