It seems to me this is all a big waste of time. Basically there are but a few MP's, and how many boats use the lake. If your a landowner this is going to go on, and on, forever and there's nothing you can do about it. Yes, you can complain, and somebody may even get a ticket one day. But the next day somebdy else will take their place. If the cove or the island is that appealing to boaters, it will be to another and another. So who are you kidding. You bought property on a public lake. Get used to it.
And as far boat operators are concerned, it seems like your state is selling you out. The goverment should be buying up these islands or condeming them so that they can remain the domain of the general public, to be used by the public, not for the rich and famous.
