Sadly we see no shortage of these events on the Maine coast. This was taken on our way out of Casco Bay heading East. All I had handy was the iPhone. My gawd these things really do take horrible pics.
Large sport-fishing boat anchors at Jewell Island. Owner drops a Fortress and all chain, reportedly backs down, he and wife head off for hike on the island, wind shifts, Fortress anchor does not reset, boat winds up on on ledge, holed and then sank = total loss..
