RedactedNarrative: On 6/17/16 at approximately 6:40 PM V-1 was heading south approximately quarter mile off of Clearwater Beach just north of Clearwater Pass.  The operator stated  that he was heading towards the pass going approximately 10 MPH when the engine shut off.  He dropped his anchor in the water and was able to get the engine to start again.  He headed towards the pass again and after approximately seven minutes the engine shut off again.  This time when he tried to set his anchor it did not hold.  The vessel drifted and dragged anchor towards the jetty at Sans Pearl Hotel.  Due to the turbulent weather conditions that day when the vessel was approximately 10 feet from the Sands Pearl Jetty the vessel capsized. The operator and all three passengers were ejected from the vessel.  One passenger was wearing a PFD because she could not swim.  All four swimmers made it safely to shore by climbing over the jetty.   The vessel was secured to the jetty with a line and Operator agreed to have the vessel removed in a timely manner.  No further action was taken.  Victim2:Minor laceration on right foot and inside of left knee; victim1:small laceration on outside of left calf
