RedactedNarrative: On 8/14/16 I began a boating crash investigation involving a 31 foot Rinker motor vessel, FL6858RA, VIN# RNK958141415. During the investigation, I identified the two males that were on the vessel at the time of the crash. 
  
  Evidence summary shows the vessel was underway when it struck a fixed object on its lower port side causing significant fiberglass hull damage. 
  
  Damage shows the port engine also separated several inches from the hull when the vessel likely reversed at the crash scene. The operator is currently unknown due to both occupants stating the other occupant was the operator. There are no known independent witnesses. The crash site is unknown. 
  
  The vessel took on water until it was mostly submerged, rested on the seafloor facing north behind 2920 Mary's Way, Jupiter, FL. Sea tow recovered the vessel that day. I spoke to the two vessel occupants during that morning and the following is a summary of events leading up to the crash: 
  
  Subject1 wanted to test drive his girlfriend's vessel with an acquaintance of his, New Port Cove Marina employee Subject2. Both men boarded the vessel in the late afternoon on Saturday August 13th, 2016. They told me that they navigated north from New Port Cover Marina. They both told me that they both had some alcohol during the initial cruise. They said they first drove by Frigate's Waterfront Bar & Grill (400 US-1, North Palm Beach, FL 33408). After that they continued driving the vessel north through the intercostal waterway to Guanabanas Restaurant and Bar (960 N Hwy MA, Jupiter, FL 33477). After stopping at Guanabanas, they then walked about 1,500 feet north to Square Grouper Tiki Bar (1111 Love St, Jupiter, FL 33477). 
  
  They both told me that an unknown amount of alcohol was consumed by both while in Jupiter. After spending time there, they left the bar and both said there was a physical confrontation while walking back to the boat (PBSO Case 16-114218). 
  
  Both men later boarded the vessel again and began to drive back south toward the New Port Cove Marina in Riviera Beach. During the voyage back both report an additional physical fight just before the crash. Both men told me that they both drove at different times during the trip back, but both stated the other was the operator at the time of crash. Both denied knowing exactly what was struck and how it occurred.
  
   Due to no independent witnesses, I was unable to determine the operator at the time of the crash. Due to both men not remaining on scene at the time of the initial marine deputies' arrival, any level of impairment could not be determined. 
  
  Photos were taken at Sea Tow's location once the vessel was removed from the water. An SD digital media card was submitted to PBSO Evidence. This concludes my initial boating crash report. Deputy Certified Advanced Crash Investigator Palm Beach County Sheriff's Office
