Jeff, i'm not sure..but most "fisheries" actually refer to the bank dont they...is it not true that.....if there is an island midstream on a fishery which has free mooring, there is no law to say you cant fish from a boat. Similarly, isn't it true that a boat can ANCHOR up and fish irrespective of whether the BANKS belong to a fishing club?....not condoning that behaviour, just pointing out.
At the end of the day the THAMES provides enjoyment for thousands of people, it allows people to take up various different sports and activities like canoeing, rowing,skulling,boating,angling, watching wildlife......
I'm sure that some of the dog walkers get cheesed of walking the banks and having to step over carbon poles and tackle that match fisherman seem to spread around themselves!
TOLERANCE required i feel.
