Prelude:  
 
A jet ski took on water and capsized near the overlook at patoka lake.  I was able to tow the vessel to a boat ramp where it was loaded on a trailer.  A report was taken.  
   
Details of investigation:  
 
On sunday september 4th 2023 i received a call from ico dispatch advising there was a capsized jet ski at patoka lake.  The occupants had got to safety but were stranded and needed help getting the jet ski to a boat ramp.  The call was received at dispatch at 4:00 pm. 
 
I called operator1 and he advised they were near the overlook at patoka lake when the jet ski started to sink and eventually capsized.  Another boater assisted them in getting to a dock where the jet ski was tied off but still upside down in the water.   
 
When i arrived at the overlook i saw a red and white jet ski on the north east side of the dock.  It was sitting high enough out of the water i could read an indiana registration number.  This jet ski registration showed operator1 as the owner and had a valid registration expiring in 2024.   
 
Operator1 explained his truck and trailer were parked at the jackson boat ramp and he did not know how to get there.  I provided a courtesy ride to the jackson ramp and he followed me to a private ramp used by the army core.   
 
I launched my jon boat and then operator1 backed his trailer into the water.  I was able to hook a rope to the jet ski and tow it to the ramp.  At the ramp operator1 turned the jet ski over and was able to put it on the trailer.   
 
Once removed from the water i looked the jet ski over for damage.  The hull was intact and i did not see any cracks or holes.  The plugs were in the jet ski preventing water from entering the vessel.  There did appear to be a dried epoxy around the intake housing.  Operator1 advised he had not had any work done on the jet ski since he had it and did not know if work had been done prior to his ownership.   
 
The passenger on the jet ski later emailed me and advised the insurance for the jet ski was through progressive.    
 
The registration showed the jet ski to be a 2003 honda marine aquatrax f-12x turbo that was ten feet in length and had a hull identification number.
