One of the community home owner's kids has placed a mooring ~75 directly off the end of my dock. Can he legally do this?
Its is 75 feet out past the dock with NO reference to how far out the dock goes
A question has been asked that nobody can answer BUT i would sure start with the HOA rules

My boat in reality is much closer to the dock than Google earth shows which is a BIG AZZ dock and there are 1000 moorings in this area and yes that is REAL VANDERBILT MANSION its the gold coast

Note: The areas designated by paragraphs (a), (a–1), and (a–2) of this section are principally for vessels used for a recreational purpose. A vessel shall be anchored so that no part of the vessel comes within 50 feet of the marked channel. A temporary float or buoy for marking the location of the anchor of a vessel at anchor may be used. Fixed mooring piles or stakes are prohibited.
The entire Long Island Sound both the NY and CT sides would be devoid of boats if everybody controlled the water 1/2 way across
