RedactedNarrative: V1- Heads WNW towards Western Dry Rocks Shoal
  V1- Strikes bottom formations at approximately 1219 Hrs causing damage below water line including keel and rudder. 
  V1- Continues WNW along shoal and then into deeper water.
  
  
  While navigating the Florida Keys Reef tract, they plotted a course along the eastern and southern side of the reef to stay in deeper water and avoid running aground. At approximately 0030 Hrs on September 29th, the vessel was located approximately six nautical miles south-southwest of Key west. The vessels course was tracking to the west-northwest. At this time the vessel ran hard aground at Western Dry Rocks Reef, Atlantic Federal Waters and inside the Florida Keys National Marine Sanctuary. 
  
  An inspection of the chart-plotter on board the S/V ‘Serenity’ shown multiple GPS coordinates inside the shallow reef of Western Dry Rocks. The chart-plotter indicated a depth of 7.9 ft before the shoaling area of lesser water depth. The draught of the S/V ‘Serenity” is 11 feet indicating that the vessel ran hard aground on the coral reef formations of Western Dry Rocks.
  
  The S/V ‘Serenity’ sustained damage to the port side of the hull (multiple striation marks and paint transfer marks), damage to the rudder(rudder post bent and shifted rudder up and aft towards the transom), structural damage to the hull( above the keel and below the water line) and fiberglass damage to the rudder (delaminated and structural damage to bottom section of keel). The damage to the vessel is indicative of a vessel that was on a starboard tack, listing to its port side when it struck the shallow reef. Most of the damage is to the port side hull.
  
  At the time of the accident, the wind direction and speed were approximately fifteen knots out of the east north east showing that the vessel was sailing with a following sea. The sea state, wind speed and vessels direction would create lee way and point the vessel towards the north. 
  
  Operator failed to act to compensate for the vessels track to the north, failed to keep a proper look out and failed to use his vessels instruments (GPS Chart-plotter) adequately. Had he watched his vessels track and heading on his GPS chart-plotter he would have
