we argue about this a lot! You have to realize that there is a current as well as wave action (or inaction). We too were there in early December, and actually stayed two nights because the water was so quiet.

Interestingly, the worst we have seen the mooring field was once when it was dead calm, and then the current kicked in. Boats were swinging every which way, with sterns coming close and dinghies bumping. We left for Trellis.
