RedactedNarrative: On June 25, 2016 at approximately 1740 hrs, Off. and I were on boat patrol on the Magothy River when we responded to an injured person on a vessel that was located approximately half a mile south of Baltimore Lighthouse on the Chesapeake Bay.  We located the 22' Glacier catamaran motor vessel bearing registration MD 4403 BL off of Podickery Point near the Magothy River.  There were 4 persons on board, 2 adult males and 2 adult females.  The injured occupant was suffering from head trauma with visible blood coming from her head.  She was conscious when we arrived on scene.  
  
  Off. boarded the vessel and I instructed the owner/operator to follow my vessel to nearby Podickery Point Marina where EMS would meet us.  Anne Arundel County Fire Department Fireboat 19 arrived on scene and followed us.  At Podickery Point Marina fireboat personnel and EMS evaluated injuries, found her head trauma to be severe, and requested Maryland State Police Aviation to transport her to University of Maryland Shock Trauma.  
  
   The owner/operator told me that they were traveling from his residence to Hemingway's Restaurant on Kent Island when they encountered large boat wakes in the vicinity of the shipping channel between Baltimore Light and Sandy Point Light.  He told me their vessel was traveling at approximately 15 knots when they impacted the wakes.  The force of the impact threw out of her seat located in front of the center console and she struck her head on the starboard side gunwale and deck.  
  
   The other occupants of the vessel were uninjured.  There was no damage to the vessel.  There was no evidence to suggest that alcohol was a contributing factor.
  
   All events occurred in Anne Arundel County, Maryland.
