RedactedNarrative: On 04/21/18 at approximately 0800 hours, i was dispatched to an area near blankenship bend on the colorado river north of lake havasu. The call was about a possible injury boat crash were several people were ejected from a vessel and the vessel was sinking.
  
  We responded via patrol boat. We arrived at approximately 0845 hours. I observed 4 male subjects on board another vessel. We were waved down and advised all 4 males were on the vessel that crashed further up river.
  
  I spoke with the operator of the vessel at this time. He advised he was traveling north near the sand bar at approximately 130 mph. Prior to the first (east bound curve) south of the sand bar, he slowed down to approximately 90 mph. As he was exiting the first turn he began to chine walk, this caused his starboard sponson to catch and spin the vessel. All subjects were ejected from the vessel but no injuries were sustained. No subjects were wearing pfds but all subjects could swim.
  
  Directly after the incident a passing boat arrived to pick the occupants out of the water.
  
  I asked what level the trim was at during the incident, he advised approximately 1/3 up. I asked if he had input any steering during the incident, he advised he did turn to the left. I asked if anyone had been consuming alcohol, he advised no.
  
  After checking operator it was determined he was not impaired during the incident.
  
  The vessel they were on had completely submerged to where only the sponsons were visible. No other damage was visible at this time but the vessel was estimated to be totaled. Towboat us arrived on scene and took over recovery operations as sgt and myself returned the occupants to the havasu marina.
