Vessel 1 was travelling eastbound, accelerating away from the boat ramp, when Vessel 1 made an abrupt turn to port (without the operator steering to port), causing the Operator to slide to the starboard side of the seat, capsizing Vessel 1.  The Operator, who was not wearing a lifejacket, then fell overboard.  Following the incident, the Operator was able to hold on to a floating fuel can; Vessel 1 sank immediately following the incident.  Another nearby boater rescued the Victim and transported him to shore where he refused treatment by the Deerfield Fire Department.
