Their lawyers will never want to take on that responsibility. At some point most of the places we enjoy with sand shores are unsafe. One of the laws of the sea is each captain is responsible for his own vessel and its safety. If a significant change is expected there is a good chance but no guarantee that someone local will knock on your hull with a heads up. If you are not at the dancing on the bar at the time? If you do not check your own weather and swell forecast late each day? You should be prepared to exit any of the open anchorages at a moments notice no matter what time the clock or contract say. If you can see open sea in any direction. One day wind, swell, and waves will come roaring in from that direction.
