One of the reasons I think the Moorings in the BVI have issues now and then is the big increase in the size of charterboats. The Moorings maintained by moor secure in general are in good shape unless the last user damaged it.
The non moor secure overnight balls (BEYC) and national park service balls can be another story. The national park service balls have a 55 foot limit that is often ignored by crewed boats and some of the bigger bareboats. That puts a lot of strain on the Moorings. I watched a large boat simply snap a park service pennant when the line came tight at the top of a swell.
