Re: Mooring bouys
I've seen 2 mooring floats drift off on their own in my mooring field during the past 2 years. They were obviously not being maintained and hadn't had a boat on them for at least 2 years.
One time, I had spent several hours locating a mooring that had lost its winter float (vandalism) and marked it with a lobster buoy anchored in the mud with a 4# sash weight. Before I got back with a new pennant and the summer buoy, someone in a Boston Whaler had picked up my "mooring"-- and was drifting off as I yelled to him.
So, as others have said, you may regret picking up a private mooring. Furthermore, you may damage tackle that was in process of being replaced, making it all the more difficult for the owner.
