RedactedNarrative: On 4/6/2014 at approximately 1330 hours Vessel 1 was operating upstream on the Coeur d'Alene river into the left hand bend between Thompson Lake and Blue Lake. Vessel 1 operator stated due to a lot of debris on the south side of the river his vessel was positioned approximately just starboard of center channel. At the same time Vessel 2 was coming downstream into the same bend making his turn to starboard for the bend. Operator2 stated he was approximately 60 feet from the north shoreline. 
  
  Vessel 1 believed Vessel 2 was going to go the south and to the starboard side Vessel 1. Vessel 1 then made a drastic turn to port in order to pass starboard to starboard with vessel 2. As Vessel 2 began to turn to port Vessel 1 turned back to starboard. Vessel 2 again tried to correct for Vessel 1's turn and turned back to starboard as Vessel 1 began to turn to port again. Vessel 2 attempted to turn to port one last time and pulled off throttle striking Vessel 1 in a bow up position at less than 10 mph as Vessel 1 crossed in front of Vessel 2. Vessel 1 did not slacken speed until after the accident. 
  
  Based on the statements given to me, I believe both operators were in violation of USCG Inland Navigation Rule 8e, slackening of vessel speed. I believe Operator1 was also in violation of USCG Inland Navigation Rule 9a1, starboard most channel navigation, USCG Inland Navigation Rule 9a2 upbound vessel gives way to downbound, and USCG Inland Navigation Rule 14a, passing port to port unless otherwise agreed. 
  
  At this time both operators have been warned and not cited.
