RedactedNarrative: According to the operator A; he and his family had left the Fiddler's Reach boat launch in Phippsburg, around late morning. They traveled along the Kennebec River in Phippsburg up the Sasanoa River in Woolwich and then up the Back River in Wiscasset to the town of Wiscasset, where they stopped briefly. They then returned to their vessel and traveled back down the Back River the same way they had come from earlier. 
  
  According to operator A, he had a chart plotter that he was using and it was leaving a track, so that he could see where he had come from. He stated that he was following the exact track that he had gone up the river from. High tide in the area was reported to be 1055 in the morning and low-tide at 1644. The ledge that was struck by operator A is known as "Halftide Rock", likely because it is only visible from half tide or less. 
  
  Operator A advised that he did see the navigational buoys but believed that because he was following his track from earlier he should have been fine traveling the same route. He advised that he was traveling at approximately 18 knots when he felt a thump and the boat suddenly came to a halt. Operator A advised the engine would still run and start but there was not propulsion. 
  
  As the tide went out the vessel became to rest at the top of Halftide Rock, approximately 8 feet above the waterlevel. 
  
  The USCG arrived on-scene shortly after the reporting and attempted to assist the vessel in distress but were not able to reach the boat. Operator A, his wife and son were also on-board. 
  
  MMP arrived on-scene with two vessels at approximately 1853 hours and were able to evacuate all three persons from the vessel and then transported them all back to their vehicle in Phippsburg.
  
  Seatow arrived on-scene approximately the same time as the MMP units and stood by with the vessel until the tide allowed them to remove it and tow it back to the owners. The vessel was returned to the owners. Seatow estimated the damages to be near $15,000.
