RedactedNarrative: At appx 6:30 AM, July 22, 2020, I was notified by SA of a boat incident that occurred at appx 9:40PM on July 21, 2020, involving one vessel and two occupants.  The incident occurred on the Intracoastal waterway’s south shoreline about one mile west of the Berwick public launch. The operator, Operator and his son were returning to the Berwick public launch when the vessel collided with a submerged object causing Operator to lose grip of his tiller operated motor.  As a result, the vessel took an immediate, un-commanded hard starboard turn then impacting the root-ball of a laid over tree sending the vessel, Operator and his son, airborne then finally coming to a rest on the port gunwale between two trees.  I contacted Operator and his son at his residence at appx 8:30 AM on July 22, 2020, where I discovered they both had injuries.  Operator had a broken nose and large contusions on his forehead, his son’s knees were had significant abrasions and swelling.  Both were checked out and cleared of any serious bodily injury by medical person.
  
  My initial investigation leads me to believe Operator and his son were returning from frogging at night and could not see his vessel fast approaching a submerged object.  As a result, when his tiller handle operated motor hit the submerged object, Operator lost control of the vessel sending it and them onto the south shoreline of the Intracoastal waterway.  Operator was wearing his kill-switch lanyard; however, because of the short distance between the vessel and the shoreline as well as, the instant trajectory change by the submerged object, the kill-switch activation did not have time to satisfactorily affect the outcome.  I do not believe alcohol or drugs to be a contributing factors.  I also do not believe carless operation was a driving factor either.
