RedactedNarrative: Boat A was a recreational boat cruising on plane northbound on the Fox River within the established shipping channel. Boat B was a commercial boat working for JF Brennan Company Inc.  JF Brennan Company is dredging the Fox River as part of the Fox River cleanup project.  Boat B was in the process of moving submerged pipeline used for the dredge activities and moving the red/green navigational buoys and therefore the main navigational channel.  Boat B observed Boat A approaching the pipeline moving operation and was concerned that if Boat A maintained course and speed Boat A would collide with the pipeline that was being moved. Boat B positioned himself in an east/west direction perpendicular to the channel to get Boat A's attention.  Boat A came down off of plane and motored towards Boat B.  Boat B maintained his position perpendicular to the channel shifting from forward to reverse to hold position.  Boat A steered towards Boat B in neutral.  The two boats experienced a minor impact.  Boat B reported no damage. 
   
  Boat A had two estimated 4 inch gouges into the gel coat on the starboard side front below the registration numbers.  A V-shaped scratch into the gel coat was also present starboard side directly below the windshield.  One side of the V -shaped scratch was about 3 inches long and the second side was about 3.5 inches long. This damage appeared to be fresh but the owner of Boat was unsure if the V-shaped scratch was a result of this incident.  Later inspection of the boat revealed several areas of fiberglass damage that was obviously old.  In particular fiberglass damage to the starboard rear corner and port bow areas.  No injuries resulted from this incident.  The Brown County Sheriff's Department responded and took the initial report although no formal report was produced.  The Sheriff's Deputy identified the operators of both boat, owners of both boats and collected registration information for both boats. There was reportedly three people in Boat A
