RedactedNarrative: V1 lost power and steering causing V1 to strike V2 (V1 bow area striking V2 stern area) and to also strike a dock piling causing it to break in half.
  
  V1 started it engines before they died again and drifted/powered out back into the channel where it was towed by Sea Tow.
  
  V1 violated nav. rule six ref. safe speed, warning issued.
  
  The vessel was a 1988, 53 feet, Mangusta, here-in-after referred to as V-1. V-1 was operated by Operator 1. There was an occupant on board the vessel that day. Operator 1was traveling south on the Intracoastal Waterway and was just North of Hillsboro Inlet in a slow speed zone.  Operator 1 had brought the occupant with him to help get the vessel to a boatyard where the vessel could be pulled to have the bottom repainted. He was operating at slow speed and heading South towards Hillsboro Inlet.
  
  V-1 was approaching V2’s home dock.  Operator 1 stated he found himself getting to close to the eastern side of the Intracoastal Waterway.  When he went to turn and power away from getting too close, he stated he had no steering and no power.  He then stated the tide and his forward momentum continued to carry him directly into the stern of V2, an 86-foot Merritt.  He stated there was nothing he could do to prevent the accident.  He stated he hit the stern of V2 and then hit a piling adjacent to V2, breaking it in half. After Operator 1 hit the vessel, he was able to start the vessel and move it out towards the center of the Intracoastal Waterway before it shut off again on him.
