If you pick some random unmarked mooring, you risk:
1 - It is 30 years old and hanging by a thread
2 - It was designed to hold a 12 foot dinghy
3 - The owner may have a more direct way of dealing with trespassers than you might like
4 - If you LEAVE the boat to go ashore for any reason and the owner comes back, your boat might be hard to find
The thing to keep in mind is that they have to be marked. As far as I'm concerned if they are not marked and there is no boat on them, its open season, use at your risk.
