RedactedNarrative: SYNOPSIS
  I responded to a medical call with the National Park Service (NPS).  The medical was the result of a boat accident, and was investigated as such.
  
  Initial Contact
  At approximately 18:50 on Saturday, May 25, 2019 in Halls Crossing Marina, UT, myself (Ranger, Boating Area Supervisor at Lake Powell) while at the Halls Crossing Ranger Station with the NPS, I overheard emergency tones for a medical call down lake (near the mouth of the Escalante Arm).  The initial call into NPS dispatch was that a male individual's leg got caught between 2 vessels. 
  
  Ranger from Dangling Rope responded. Classic Air Medical was requested, but a helicopter was not available. Eventually NPS dispatch contacted Ranger and stated that a helicopter was availed and they would launch. Ranger requested that Ranger/Paramedic responded to the scene (as did I). We arrived on scene at 19:56 at the floating restroom at Buoy 67. Dangling Rope Rangers were already on scene. I observed Ranger in a white/gray Malibu wakeboard boat treating a male patient. The white Malibu wakeboard boat (identified as Vessel 1 in this report) was tied up to the floating restroom at (Buoy 67) close to the mouth of the Escalante arm of Lake Powell.
  
  Medical Call
  I observed Ranger in a white Malibu wakeboard boat treating a male patient (identified as Victim), Ranger1 stepped on board the vessel Victim had a severe laceration to his right ankle (later described as a "maceration" to me by Ranger1). For medical reasons (interactions with pain medication) Ranger1 administered a portable breath test (PBT) to Victim, which showed positive for the presence of alcohol. The reporting party had contacted NPS Dispatch via the radio on Marine Band 16 and transported Victim to the floating restroom at Buoy 67. Victim was packaged up and wrapped in a blanket, and secured to a backboard to prepare him for transport with Classic. Both NPS vessels on scene, and all NPS rangers transported Victim from the floating restroom to an LZ by the mouth of the Escalante to meet the Classic Air Medical crew.
  
  Investigation
  I asked Subject1 to describe in detail what had occurred. He also provided me a written witness statement as well. As did Subject2 and Subject3 as well. He stated that Subject2 (who he described as an unfamiliar boat operator) was pulling the Malibu wakeboard boat (Vessel 1) up next to the houseboat (Kokopelli's Mojo - Vessel 2) to tie up. Subject2 was the only individual onboard Vessel 1. Subject1, Victim, and Subject3 were onboard Vessel 2. Subject1 stated that "she was pulling in too fast" and Subject2 in her written statement stated that "as I started coming closer to the boat, I went to put the boat in neutral but instead revved forward causing the little Malibu to head towards the houseboat (back end)". 
  
  Vessel 2, the houseboat was parked onshore when the accident occurred. Subject1 was not on board his boat (the white Malibu - Vessel 1) when it hit the houseboat (Vessel 2). He is listed under Vessel 1 as the owner. Subject1 stated that Victim's foot was "bleeding pretty bad, could see bone through skin".
  
  Subject1 did state to me that he thought wind was a factor, and so did Subject3 in her statement. Subject1 stated that the location of the accident was "about half way up the Escalante Arm on the right side. He said they weren't in a named canyon. Subject1 also confirmed to me that there was no damage to either vessel. Vessel 1 had Maryland bow numbers, but had temporary current Colorado registration). Subject1 stated he just purchased the vessel recently, assigned Colorado bow numbers.
  
  I observed a can of White Claw (alcoholic hard seltzer) in the driver's compartment cup holder, just below the throttle. I asked Subject1 how many alcoholic beverages he had consumed; he answered approximately 4-5, with his last drink being around 14:00-15:00. He stated the White Claw can was not his and that he wasn't sure whose it was. At this time due to his self-admission of consuming alcohol that day, and the opener container, I decided to have Subject1 do Seated Field Sobriety Tests (SFSTS). I administered SFST's and the vessel operator (Subject1) performed SFST's. I observed 6/6 clues on Horizontal Gaze Nystagmus (HGN's) tests, but minimal clues on the other 3 tests (finger to nose, palm pat and hand coordination). I did not detect an odor of alcoholic beverages from Subject1 and observed his eyes to be slightly glossy. The portable breath test administered by me to Subject1 showed negative for the presence of alcoholic beverages. My PBT was used, and also an NPS PBT. Subject1 was rendering aid in an emergency situation, to get medical care and assistance for his friend Victim. He was cooperative and complaint throughout my contact with him. Subject1 showed negative for the presence of alcoholic beverages. Subject1 and subject4 confirmed to me that Subject2 was driving Vessel 1.
  
  Classic Air Medical, flew Victim to Page. Ranger1 later stated to me that due to inclement weather, Victim was later transported to St. George via fixed-wing aircraft. Due to the incoming storm, and it getting dark, the Halls Crossing and Bullfrog rangers started to head back to Bullfrog, and Subject1 headed back to their houseboat.
  
  Based on my investigation, my interview with Subject1 and witness statements from the parties involved, I believe the strong winds and operation inexperience were factors in this accident.
