  DC Harbor Patrol vessel 800 and DC Fire Boat 2 and 4 were also sent to the location. While en route, the USCG removed the female victim from the vessel and transported her to Georgetown pier and began CPR. No notification was made by the USCG to DC Harbor Patrol that the female victim was no longer at the scene. DC Fire Boat medics were rerouted to Georgetown pier when DC 
  
  Harbor Patrol vessel 800 observed USCG operating on plane towards Georgetown pier and investigated further. Harbor Vessel 800 was advised by the on scene USCG personnel that the owner of the listed vessel was still on-board his anchored vessel and he too was exposed to the Carbon Monoxide.  Harbor Vessel 800 responded to the listed vessel and brought the owner to the

  The listed vessel had all of its hatches and portholes opened to vent the vessel and it was towed by the DC Harbor Patrol back to the Harbor Patrol Base for safekeeping until the owner could retrieve.
