RedactedNarrative: On 08/31/18 between 8:45 PM and 9:30 PM, Vessel 2 was traveling north on the North Branch of the Chicago River near Grand Ave. Vessel 2 docked his boat on the East Wall of the river near the Erie Cafe.  Vessel 2 docked behind a boat was tied up and unoccupied.  As Vessel 2 was securing the boat, Vessel 1 was traveling North on the river.  
  
  In a written statement, the operator of Vessel 1 stated he operated past Vessel 2 and the unoccupied Vessel leaving a normal sized wake that a Chicago Water Taxi would leave and continued to his dock.  Written Statements from those aboard Vessel 2 state Vessel 1 was operating well above No Wake Speed.  The wake from Vessel 1 caused Vessel 2 to strike the wall, on which it was docked, several times.  The statements also say the wake also caused the unoccupied Vessel in front of Vessel 2 to have its rear dock line snap.  The operator of Vessel 2 traveled up river to where Vessel 1 docked at its place of business.  The operators of each Vessel had a verbal confrontation about the incident.  Each of the conversations can be found on their respective attached written statements.  
  
  CPO checked with local businesses near where the incident occurred in an attempt to locate camera footage of the Vessel''s traveling on the North Branch of the Chicago River.  CPO was able to obtain several videos showing footage of Vessel 1 operating at above No Wake Speed near where the incident occurred.
