Somewhat relevant to this thread:
It always amazes me that people will just tie up to any old mooring they find. There was a thread about this here awhile ago, as in some places you can do that under the assumption you must leave if the owner shows up. Was that mooring designed for small skiff or daysailer, or a boat your size? When was it last maintained?
We like using moorings, but do so only if it is a commercial/government field and we have confirmed with the harbormaster that it is appropriate for our boat.
One exception was in the beautiful Thimble Islands off Connecticut. We were in the process of commencing anchoring in a lovely, protected spot, and a guy came by in a skiff on his way to his dock, and offered the use of his mooring, assuring me it had just been serviced and they'd had as much as 70 footer on it.
Moorings come in many different designs. We always try to use as much of our own ground tackle as possible. I learned this quick at Vero Beach when the painter designed to go over your bow cleat broke off in my hand. I brought it in with me when I checked in, to the chagrin of the staff. We noticed a bunch of people around us in the field busily changing their hook-ups over the course of the day as word got out....
