RedactedNarrative: On July 30, 2015 at approximately 2:45 PM, I responded to a call of a vessel taking on water with possible people in the water near Haulover Inlet. At approximately 2:55 PM Officer was the first on scene and advised that the vessel was completely submerged in the water and that 2 POB's were safely aboard a North Miami Police Marine Patrol vessel and the operator was safely aboard a Fast Response salvage vessel. 
  
  At approximately 2:55 PM I arrived on scene to assist with picking up several large pieces of debris that were floating from the vessel. I approached the salvage vessel to pick up the operator from Uruguay. Once I had Operator aboard my vessel I proceeded to the Haulover Fuel Docks with the NMPD Marine Patrol unit. At approximately 3:15 PM we arrived at the Haulover Fuel Docks, I began to gather information from Operator in regards to his vessel. 
  
  Operator advised that they were traveling southbound approximately 1/2 mile to 1 mile off shore towards the Haulover Inlet. While operating the vessel Operator stated that he heard a very loud abrupt noise coming from the aft of his vessel and then lost power to his motors. Operator opened the engine compartment and realized that there was water rushing into the compartment at a fast rate. Operator retrieved 2 PFD's and gave one each to his 2 occupants aboard.  Operator stated he called for help over Marine Channel 16 and advised his vessel was taking on water. Operator was able to flag down a good samaritan that was nearby and transferred the 2 occupants to that vessel. Operator stayed aboard his vessel and threw out his anchor in the efforts to salvage the vessel that was still taking on water at a fast rate. Before the vessel was completely submerged Operator was picked up by a Fast Response salvage vessel. 
  
  There were no injuries as a result of this accident. Operator did state that he had a functioning bilge pump onboard. Fast Response was hired by Operator to re float and removed the vessel from the water. It is possible that the engine cooling hose burst.
