Several years ago, anchored in the SE corner of Great Harbour, Peter Island, BVI, with a superyacht anchored out near the mouth of the bay, a mess of water toys deployed and well into party mode.
Later, well after dark, the wind had dropped and then returned, blowing in, rather than out. The superyacht's tenders went to all of the anchored boats downwind of them, asking them to move out of the way, as the SY was dragging. We were close enough to shore that they didn't come that far in.
Before dawn, I woke to a light tapping, went up to investigate and found a similar sized sailboat tapping against our side. I pushed it away and put on the coffee. Some time later, after pushing the visitor away a few times, its occupants came up on deck to discover where they had re-anchored. The water was clear enough we could both see their anchor on top of ours.
No harm, no foul.
