RedactedNarrative: On 9/6/2015 I was dispatched to Chestertown Medical Center for a head injury on a vessel.  Upon arrival I spoke to subject.  She stated that their vessel was docked in their slip at Rolphs Wharf.  She said she went to get up from the table and slipped and fell against the cabin of the vessel due to the vessel being tossed back and forth by a wake.  Victim hit the top of her head and ended up with 10 staples and a slight concussion.  I spoke to another person and he stated that the vessel was being rocked back and forth roughly because of the wake that boaters were causing by the marina.  Rolphs Wharf Marina is located in a Sat, Sun, and Holiday speed zone on the Chester River.
   
  On 9/7/2015 I spoke to two others.  They have a vessel docked at Rolphs Wharf at slip.  They stated that they were there when the incident occured and believe it was due to the wake caused by vessels that were passing through.
   
  No one was able to identify a specific vessel that caused the wake but there have been a couple times where their vessels had been tossed roughly due to vessels speeding through the speed zone.
  
  All events occured in Queen Anne's County, Maryland. .
