If you google the story, you can see some photos of some moderate surf pounding her up against the rocks.
A sailboat was on the rocks there less than two weeks ago. It also appears Elsa had fuel leaking per one story. They are beginning salvage efforts now. http://www.saba-news.com/saba-conse...ntity-saba-respond-to-second-yacht-stranding/ Also, going to reexamine all their mooring.
I am ignorant on proper mooring watch procedures on large motor yachts but it would seem to me that there should have been crew on watch to be sure that things like this do not happen?
