Strowie, there are now I believe well over 12,000 private craft on the Broads,so the chances of being bumped by the remaining 750 or so hire craft will IMHO, increase the ratio of possible accidents.
There will always be the "skipper" I use that word very loosly who could receive two hours instruction, and still cause mayhem once out on the rivers. All many can think of is.....where can I stop, yes stop, not moor up to get to a pub!
I have heard and seen it with my own eyes, its not right, that goes without saying, but, the Norfolk Broads is a HOLIDAY area and you just gave to grit the old gums and hope it never happens to you.
If it does, then numbers exchanged and boatyards informed should be rule of thumb.
