From what we can see...

1. Moorings vessel

2. looks like he used a double bridle to the mooring .

4. looks like the mooring can and its anchor drug toward shore being pulled by the weight and resistance of the boat due to the conditions.

5. Our last BVI trip, May 2017, before Irma., two of us on the jeanneau 36i.... we intended to moor at Diamond Cay, Jost Van Dyke, and go to dinner at Foxys Taboo....But it was open to the SE strong winds wind and swell . We needed a NE wind,
not SE.

6. Also tried Great Harbor, although other vessels were moored and the harbor looked full, we passed Due to the SE winds and swell, it would have been a very rough night. Inside the harbor the conditions had boats boundiing and bobbing about..

7. Motored , yep, over to Canegarden Bay, where the wind was still howling and white caps at the pass entry. But, as we got in the lee of that big hill, the wind and windwave conditions went to near zero and flat. Much more comfortable and safe.

We had a very calm night on board after a good times at Myetts. For us, with all of Josts harbors open to the wind and waves, no way for us to moor there . But, that is us. A whole lot of other boats thought different. We are hoping the NE
wind conditions will bless us this coming may and allow us to moor at Jost.

Of course, we were not there in canegarden during this presented incident, and can only surmise from looking at the photo....But great care should be taken when a mooring field or anchorage is open to strong winds and wave conditions.
