RedactedNarrative: On Sunday, March 23, 2014 at approximately 2248.  I responded to call regarding a grounded vessel. The vessel was located south of fisherman's channel and northwest of the virginia key no entry zone , within miami- dade county. Upon my arrival i spoke with the vessel operator. The operator advised that one of the passengers was taken by paramedics and transported to the hospital (ryder trauma center) for minor injuries. Ofc went to the hospital and identified the subject. Afterward, i took a written witness statement from the operator, he stated that he was crusing northbound toward fisherman's channel when the vessel ran aground. The impact threw subject into the deck causing an injury to his chin. No other persons onboard were reported injured at that time.
