We had two visits too.
On the first visit, when the photo was taken, we picked up the buoy nearest the jetty, so it was open to the swell. Still not sure why the swell was so bad, there had been very little wind for the previous few days. It was the day before the new moon, and HW was at 01.46 and the swell seemed to start at 04.00.
I got up and tried various ploys - tried to paddle the stern round - tried the rudder at various angles - all to no avail. The boat on the next buoy was leaving, so whilst he had his engine running to warm up, I ran in reverse to pull the stern round - it swung back as soon as I stopped. I got the bow pointing into the swell by having the line on the pickup buoy at its maximum length to the bow and bringing my back up line to the stern but it only worked for a short time before we swung and then had the main buoy banging against the hull. It did calm down eventually because I went back to my bunk for a while.
We returned a week later, picked up a buoy on the line nearest the shore, but furthest away from the jetty so that we might get some shelter from Goat Island. Didn't have any problem with swell.
BTW - what are the dynamics involved which makes a boat lie beam on to the swell in the absence of wind or tidal flow?
