I had a night caused by a Thunderstorm in WB I will not forget. Had a boat drag down on us at 3 AM and snag our anchor chain. A mess to sort out with waves breaking over the reef. The mono that snagged us was being slammed down on its keel in the troughs of each wave.
I also watched a Moorings 4300 drag onto the reef after a 90 degree wind shift while crew was ashore.
