RedactedNarrative: Vessel - 2001, 27' 7" Fiberglass Donzi 28 ZX Open Motorboat w/2 300 hp Mercury Sterndrive Engines 
  
  On 09/01/2014, at about 08:20 p.m., this vessel was cruising on Lake Washington located near Kirkland in King county WA. According to Law Enforcement, the boat was headed South from Houghton towards Evergreen Point. 
  
  In the area North of Yarrow Point, Operator1's vessel was crossing behind Witness's boat. After Operator1 passed Witness's boat's wake his boat reacted to a rogue wave/wake by hooking to starboard, spinning the boat out and stopping suddenly. Operator1 stated he was travelling about 35 mph and did not see the other wave/wake that caused his boat to hook. 
  
  This action caused Operator1's passenger, Occupant, to fall out of the port front seat striking her side and head on the inner portside of the boat. She lost consciousness. Operator1 also was forced from the starboard helm, falling to port striking the top of his head causing a small laceration and then landing on Occupant. The other passenger was seated in the back seat and was not injured. 
  
  Operator1 stated that they had been on the water since 1:00 p.m. and at dinner in Seattle both he and Occupant had alcohol at dinner but were not intoxicated. An assessment of Operator1 by Law Enforcement did not indicate impairment. No enforcement action was issued. Occupant was transported by aid to Overlake Hospital for treatment of her injuries. Operator1 later went to Overlake Hospital by private vehicle for treatment of his cut head.
