Several times this season I have returned to my mooring after an afternoon sail to find a boat hanging on it. This never happened in previous years. Any thoughts on why people seem to feel it is OK to take an obviously private mooring in a harbor with abundant rental moorings. Fortunately the people have been on the boat each time and moved when asked. None of them apologized though. Anyone who pulls up my pennant will find it nice and clean indicating it is in regular use.
