It is for us; all of us, not just boaters. The NT is trying to manage things for as many people as possible not just particular interest groups. Personally I think they do an excellent job.

Your arguement is the same one the travellers used when they wanted to do just as they wished at Stonehenge a few years ago. (I know Stonehenge isn't NT property, but the point remains).

There are miles of beach to use elsewhere.
