Well said Mal
I have not seen the program , but it is shocking that water companies get away with the current situation.
I live near the stour in Wimborne, but would not swim in it, even in these heatwaves.
Personally the one I use has a shorter warp as what I have had on occasions if there is a swell, the buoy has gone the wrong side of the bow.
What I do as I think others do too is go astern before going forward, just gives abit more space between boat and anchor rope/buoy.
