Dip continues

9-30 hrs: dip continued again after a day or so - shortage of breath with associated feelings of weakness and so on - which is annoying as there are things I want to do. I have not taken the boat out again - tides are wrong and the weather is not encouraging either.  The most interesting thing round here is that they are digging up the sea wall downriver from the sailing club: apparently tidal scour is threatening it. Today's task - apart from shopping and the like - is to take pictures from the land - hard to do as it is fenced off.
