Actually what is needed is a proper mooring
There used to be one, near Tuffy dive site by the main San Pedro channel. A large concrete block with integral hoop for securing a line is still there. It was tipped over 30° by Hurricane Dean but I should think is still usable. The whole time I've lived in SP there hasn't been a mooring attached to it, but it wouldn't be difficult to reattach a rope and buoy.
Of course, there would have to be a monitored radio service and people prepared to run tenders out to a boat mooring there. And it would only be usable in calm conditions.
On the controversy, we really have no idea what the facts are and it would be foolish to pre-judge. But sadly "rich" and "arrogant" often go together. No idea whether it does in this case, of course.
