RedactedNarrative: On September 3, 2017 at approximately 1600 hrs I responded to a mayday call on the marine VHF radio of a vessel explosion on the ICW north of the Hillsboro Inlet. Upon arrival I observed a 35 ft Sea Ray with a w/m on the bow waving me down. 
  
  As I approached the vessel the w/m advised that there was an explosion in the engine compartment that blew his son off of his seat, and on to the swim platform located on the outside of the stern of the vessel. He further advised that his son was picked up by a nearby vessel, and motioned to where that vessel was located. 
  
  I asked the w/m if there was any other people on the vessel, and if anyone was injured. He stated that his wife was onboard but was not injured. I located and pulled along side the vessel that had picked up the son. I asked him if he was injured and he replied that he was not. He stated that he was sitting in the seat facing the stern when he observed smoke coming from the engine compartment. He further stated that there was an explosion that threw him into the air causing him to land on the swim platform on the outside stern of the vessel. 
  
  He advised that he then jumped into the water and swam to the vessel that picked him up. I placed son on my boat and pulled back along side the 35 ft SeaRay. I instructed the owner/captain of the vessel, to get on to my patrol vessel along with his wife, and their dog. I pulled away from their vessel to a safe distance until Lighthouse Point Fire/Rescue responded (Engine/Ladder 22) and was able to deem the vessel safe. The vessel was towed by Boat US to LHPM until the vessel could be removed from the water. No injuries were incurred as a result of this incident. A case card was issued.
