RedactedNarrative: On Tuesday, April 14, 2015, at approximately 9:50 am, operator was operating and traveling northbound along the Intracoastal Waterway (ICW) in a 2013 38' North End Marine (FL 7672 PK). The vessel struck channel marker 37 east of 3 Rooker Bar in Pinellas County. The impact caused a minor injury to Operator and extensive damage to the vessel. 
  
  At the request of subject, the vessel "Low Key", was being relocated from Marker 1 Marina in Dunedin to Tarpon Yacht Services in Tarpon Springs for a short haul to repair a leaking transducer. Operator was traveling northbound, along the Intra coastal Waterway (ICW). The auto pilot was engaged while traveling east of Three Rooker bar. The speed of the vessel was 27 kts. Operator advised, the auto pilot was steering the vessel on a steady course, but "fish tailing". At that time, Operator noticed the GPS was tracking a way point. He disengaged the "planning mode" to attempt to stop the GPS from steering to an unknown way point. Operator stated, that immediately after disengaging "planning mode", the vessel turned sharply to port. Before the throttle could be pulled back and auto pilot disengaged, the vessel struck Channel Marker 37 on its port side (See Attached Photos). The impact knocked both sides of the channel marker's placard onto the bow of the vessel. The vessel came to a rest approximately 200' west of the, then bare, channel marker post (See Attached Diagram). 
  
  Operator contacted the Coast Guard on VHF channel 16. Coast Guard requested a cell number and contacted Operator immediately. Coast Guard discovered (via cell phone), that the vessel was not taking on water and that there were no injuries beyond first aid, he only received a bruise to a knee. It was determined by Operator, that the vessel was still operational. After Operator confirmed that the vessel was "sea worthy", he proceeded to the haul out facility (Tarpon Yacht Services). There the vessel was pulled from the water and stored. The vessel remains there at the time of this report. Coast Guard referred the incident to FWC.
