RedactedNarrative: On August 5th 2019 I chartered a 31' O'Day sailboat (S/V Fletch} from Buck's Harbor Marina and proceeded south in eastern Penobscot Bay. Due to light winds we decided to motor through the channel between the Barred Islands and Great Spruce Head Island. After passing the last island in the channel I turned east to pass north of N "2" (west of Eagle Island and NW of Fling Island). I felt I was far enough north to avoid the rock indicated on the chart but ran aground north of the nun at approximately 1450. 
  
  Attempts to back off the ledge were unsuccessful, so I placed the anchor and 25 feet of chain rode in the dinghy and dropped it approximately 25 yards to my stern to use as a kedge. I also hoped it would lighten the bow of the vessel. Using winches to haul this in with the engine in reverse was not successful. At this point I put out a distress signal and requested assistance. Within about 15 minutes a fishing vessel approached and using the dinghy I brought them a tow line but the boat was unable to dislodge the boat off the reef. Soon another fishing vessel arrived (TM II out of Eagle Island) and they tried pulling in different directions while the other vessel made waves to help bounce the boat off the ledge. Heeling the vessel with the main halyard was also unsuccessful. 
  
  Eventually a tow boat arrived who again tried to pull us off but only succeeded in pulling off the remaining cleats. He then insisted we abandon ship and he was able to get close enough for us to safely disembark. At that time the owner of the vessel arrived and stated he would assume responsibility of the boat while Captain delivered me and my one crewmember back to Buck's Harbor Marine along with the motorized dinghy. Neither of us sustained any injuries. 
  
  At no time did we observe any fuel or oil leakage and there was no debris in the water with the exception of the anchor which was cut free after it became snagged on the ledge. I have been informed that subject successfully removed the diesel fuel from the boat. 
  
  The current status of the vessel is unknown to me. I was told it was no longer on the ledge but have no way of verifying this. As it was not my vessel I felt I did not have the authority to turn it over to a salvage company or otherwise attempt to recover the boat.
