False start this morning...we were planning to leave between 9 and 10 to go through lock but 2 peniches went by before us and when we finally cast off (trying to stay still in front of closed lock to show lock keeper we were ready) lock keeper came to say he was waiting for descending boat and therefore we would need to wait.

Lack of water means boats have to "go together". We don't mind. It is all good practice as I have always thought that staying still was probably the most difficult thing to do on a boat (well, for us at the moment) and we only have to take notice of wind and prop walk. No tides!
So now, it's 11 o'clock, and we are waiting.
