RedactedNarrative: INITIAL NOTIFICATION
  At about 1230 hours, a boater notified me on the marine band radio channel of a PWC towing a person into the marina as they were hanging onto the PWC. The reporting boater was concerned about asphyxiation for the person being towed. 
  
  RESPONSE
  I responded by boat to the area and searched for the PWC/person being towed. After a few minutes, I noticed a PWC stopped in the water about 200 yards northeast of the marina so I made contact and found it was likely the PWC reported. There was a male attempting to re-board the PWC from the rear but he was struggling to reach the seat and partially laying on the rear of the PWC in apparent exhaustion.
  
  ASSISTANCE OFFERED
  I brought the patrol boat along side the PWC and offered VICTIM the rail of the patrol boat to help stabilize and pull himself up as I held the PWC by it's handle bars. The US Coast Guard Auxiliary arrived at our location and offered to help as VICTIM was pulling himself up onto the seat. Once VICTIM was on the seat, the rear of PWC began to sink and pull away from the patrol boat. As the boats pulled away from each other, VICTIM kept hanging onto the patrol boat rail and subsequently fell back into the water.
  
  
  As VICTIM fell back into the water, he continued hanging onto the patrol boat with his left hand. The US Coast Guard Auxiliary made their built-in ladder ready and had VICTIM swim to it and board their boat. After VICTIM was on the USCG Auxiliary boat he mentioned that he was unable to use/lift his left arm. I offered to have medical units/EMTs respond to help but VICTIM denied medical assistance. VICTIM said he would find somewhere to get it checked out. We then discussed local options for medical facilities and I gathered some information for report. The operator of the PWC was VICTIM's wife and I believe there was also another female as a passenger on the PWC. The other female was his wife’s daughter. Once VICTIM was on the USCG Auxiliary boat, the two females on the PWC started driving toward the marina to meet with VICTIM on shore.
  
  CONCLUSION
  VICTIM concluded that he must have injured his left shoulder when he fell back into the water still hanging onto the patrol boat. The USCG Auxiliary transported VICTIM to the marina pump-out dock where he off-boarded and thanked all for the help.
  
  FOLLOW-UP
  Later in the evening of day of incident, I called VICTIM to see if he was able to get checked out at a medical facility. He said he was still planning to get checked out further. I gathered additional information needed for report.
  
  On 9/7/2017, I called VICTIM to get information for the female passenger. He gave it to me and I also found he just returned from an appointment where he learned he will need surgery for the injury.
