The "WHY" is quite simple and I have already explained it. The playing field "must" be equal. As has been explained re Private Access for the 2013 Nationals. " If all fishermen cant have access to the area, no one can" The same would stand for boat access. ie "if everyone cant get to it then no one can" Quads and 4WDs dont give you access to ledges accessable by boats and only make the carrying of gear easier. Sure they open up more beach for you but that is all. Ask as much as you like I will stand against it. I was surprised that at the start of this thread you wanted to keep aircraft out of it.
