it is a local diving club, they may be able to put you in touch with a local diver.
Over the last couple of weeks we have had a team of divers working in the Marina cleaning the Basin walls, you could try ringing Dan McKiernan the marina manger 01634 899200 to see if they are still working.
A mate of mine whose a special Constable tells me that you'll find a diver on Rochester High Street on a Friday or Saturday evening. They apparently normally wear fishnet tights and VERY short skirts and tight tops. I've absolutely NO DOUBT that one of them will help you with your anodes.
Col, if you see a Broom 1070 alcedeo atthiss, say hello from me to him, Dave is on the MBM cruise east coast he is a good friend of mine, not seen any reports of the cruise at all, ???????
