RedactedNarrative: Vessel was moored on the SE side of Bear Island in the Apostle Islands.  Two passengers were on-board, sleeping.  The winds shifted during the night from west to coming out of the south causing 2 foot waves from the south.  Shortly before 8:00 am, the mooring shackle on the vessel failed causing the anchor to release.  
  
  The vessel ran aground at approximately 8:00 am, waking the two male passengers.  The Passengers found they had already grounded and waded to shore.  The USCG and National Park Service were notified and picked up the men from the island.  The waves build from 1-2 foot to 3-4 foot and the salvage company was unable to retrieve the vessel until 4 days later, which left the vessel on the beach.  During that time, the vessel took on water and sank in the shallow water.  The turbulent conditions caused sand abrasions to the portside of the vessel and 3 ribs cracked under the pressure.  After the incident occurred, the salvage company arrived to retrieve the vessel and cause more damage during the retrieval.
