We spent our last night out at Cooper, and while it wasn't the calmest night, neither of us is much bothered by the bouncing around. We were on an outside mid-field ball which was probably a bit rougher, but we didn't spin around.

I chose Cooper over Norman (which would have been calmer), because instead of a bash to windward we had an easy beam reach back to Road Town.

An M5000 (Sea Sprite) took a mooring near us and tied up with a single line through the pendant eye fastened to the crossbeam cleats.
I try to avoid involving myself, but ended up dinghying up to them and after apologizing for the intrusion and asking if they were the owners of the boat, I said I wanted to make sure they knew that this was not an adequate tie-up.

They did (kind of) correct the situation, but saw the boat back at the base yesterday, so I have to assume that they tied up in that manner for all but the last night of the trip. :-(
