RedactedNarrative: On 04-08-16 at about 1430 hrs., I (Dep.) was dispatched to a non injury vessel collision which occurred on Lake Coeur d’Alene at the Boardwalk Marina.
  
  Upon my arrival, I contacted a security guard for Coeur d’Alene Resort.  Guard advised me one of Hagadone Hospitality rental boats had collided into a patron’s boat while at the gas docks.  
  
  As I walked onto a Boardwalk Marina gas docks I observed a Bayliner Ciera 2455 with large gouge in the fiberglass on the port side of the swim platform, a large hole in the port side transom, a blue paint transfer along the hull of the starboard side and paint transfer and abrasions along the starboard side rub rail.  I observed a Cobalt 220 with the mutable fiberglass fractures and fiberglass chipping at the bow of the vessel, fiberglass damage to bow eye plate and the red and green navigation light dislodged from its affixed location only connected by wiring. I also observed a MSD tank pump out station knocked over laying on the dock with one hose broken and two still connected. 
  
  I contacted (D1) and asked him what happened and he told me the following: He and his wife (P1 and children had boarded the rented vessel.  The staff at the Boardwalk Marine provided instruction on the operation of the vessel. Once they were done and exited the vessel Operator started the vessel. He applied the throttle, but accidently applied to full speed causing the vessel to travel directly forward hitting the port side transom of the Bayliner which was tied to the dock in front of him.   Operator stated it happened so fast he had no time to avoid the collision. 
  
  I contacted owner of Bayliner (O) and asked him what happened and he told me the following: he had pulled his boat up the gas dock to get some fuel and snacks.  His vessel was tied to the dock.  He and his wife (M) exited the boat.  As he was walking in the marina  he heard a crash. He turned around he see damage to his vessel and the Cobalt drifting away from his boat.  
  
  I contacted (W) and asked him what happened and he told me the following:  He explained he is an employee of Hagadone Marine.  He stated he provided the safety information to Operator per his training.  He stated the customer, Operator aggressively thrusted the throttle into full speed causing the vessel to travel forward colliding in to the Bayliner tied off in front of him.  Subject advised the operator to place the throttle in to neutral.  
  
  I recontacted  Guard who advised there was a Hagadone Hospitality pontoon boat which was tied to the dock in front of the Bayliner that also sustained damage to the cowling of the motor .  Guard stated the vessel was no longer on scene but would return.  I asked Guard to photograph the damage and bow number and email me those photographs. 
  
  Based on the statements and my observations I believe Operator rented a 2016 Cobalt 220, received instructions from Hagadone’s Hospitality staff (unknown exact instruction), boarded the vessel with his wife and two children, started the boat applied the throttle to max speed hitting the Bayliner tied to the dock in front of him.  The Cobalt hit the port side of the swim platform first, forcing the vessel to pitch up hitting the Bayliner’s port side of the transom causing the Bayliner to yaw starboard, pitching the front of the Bayliner onto the dock hitting the MSD tank pump station. The Bayliner slid back down into the water with the bow hitting the motor cowling of the pontoon boat tied off to the dock in front of the Bayliner.
  
  I photographed the scene with my department issued camera.  The photographs were saved to a CD and booked into evidence.
  
  I believe Operator was at a speed unable to avoid collision, inexperienced, negligent, and did not take proper action to avoid collision. At this time Operator has not been issued any citations.
