RedactedNarrative: On 09/01/2014 at approximately 1130 hours I was dispatched out of my district to a report of a boat accident in Navajo Canyon.  I was informed that an Aramark tour boat had struck an open motorboat.  Upon arriving on scene, the passengers of the open motorboat, an Antelope Point rental boat, had gotten a passerby to tow their vessel back to Antelope Point.  The passengers (10) were divided into two groups, 6 or them boarding NPS Vessel 252 with Ranger, and 4 additional boarding my vessel to include the dirver, as the rental boat was taking on water and was not safe to have passengers aboard. 
  Upon interviewing the Captain of the tour boat, by Texas driver''s license, he stated that he passed a house boat in Navajo Canyon on plane and then heard a collision that he at first thought to be a marker buoy.  As he looked behind him he stated that he realized that his vessel had struck a small ski boat, and he promptly turned around to render assistance.  He further stated that several of the passengers had jumped into the water, apparently to avoid an impending collision.  I took Captain aboard my vessel and performed SFST''s which were negative, and he had a BrAC of 0.000.  I took him around his vessel while I was taking pictures, and Captain stated that he could not identify any new markings or damage to his vessel.  
  After gathering Captain witness statement, the Nonne Zoshi continued back on towards Wahweap as I brought the additional passengers from the rental boat back to Antelope Point to continue the rest of my investigation.  The driver of the rental boat wrote a witness statement as well as one of his other passengers.  Their statements corroborated that while they were not under power, and pulling in a tube, that the Nonne Zoshi headed straight for them on plane without any indication of changing course.  Subject stated that an attempt to start the boat failed, and they could not get out of the way.  Both statements state that several members of the group ran towards the bow with four of them opting to jump into the water.  Operator2 had a BrAZ of 0.000.
  I reunited the driver and 3 additional passengers with their group at Antelope Point.  I found the rental boat by boat rentals and took pictures.  It seems that upon interviewing all parties that while on plane the Nonne Zoshi basically ran over a stopped 22 foot open motorboat in the center channel of Navajo Canyon.  The damage sustained to the rental boat is extensive.  From the damage profile, written statements and verbal statements from the additional passengers from the rental boat, it appears that the Nonne Zoshi struck the back of the rental boat with it''s bow.
  subject suffered a small scratch on her right lower abdomen, but other than that, all other members of the rental boat crew were uninjured and did not want or need any medical care.
