I had intended to remain quiet on this one whilst debate is taking place on Facebook on a dedicated thread but there are a few points that perhaps will help this discussion.
Whilst I can't prove it, I was party to a personal debate with John Packman and Trudi Wakelin where it was made perfectly clear that both anglers and boaters would have to accept some limitations as to where they could go in the interest of conservation. Proposed 'special directions' in the draft Broads Bill, on record, were clearly intended to have the power to exclude boats from specific locations. At no point, either in conversation or in the Broads Bill, was there any suggestion, or even the faintest hint, that boating would be banned on the Broads, just that limitations and controls were needed in order protect specific locations. We must be realistic, the BA exists on our money, over 50% of their money comes from our tolls. However, as Paladine has pointed out, we mustn't forget what happened at Horsey, or that Cockshoot is still closed to navigation.
Personally I see Sandford as a very real threat, despite assurances. The big push could come from elsewhere, not necessarily the BA. It could also apply to many activities, not just boating and angling.
Back into my cupboard.
