We were the first down onto the good old Portland Dredger. Spent much of the dive practising underwater navigation. My compass kept on sticking but knocking it seemed to do the trick. We swam along the rocks at the side of the harbour and saw a riot of autumn colours. It was incredible to see the reds, oranges and yellows on the sea bed echoing the colours on the land. As we moved along we were picked up by the current washing over the rocks and I experienced once more the strange illusion of seeing huge rocks swaying back and forth (in fact of course it was me). Graham found a pipe fish which is long, thin and snake-like with a little mane running along its back. I held it and it squirmed in my grasp before I released it. An excellent welcome back British dive.
