RedactedNarrative: On March 17, 2015, Subject and his wife were on V1 at anchor watching the sunset over the Gulf of Mexico.  They were located near Marker #8 of the Pithlachascotee River.  Subject2 went into the berthing area of V1 and observed that it was full of water.  Subject then quickly checked the bilge area, and it too was full of water.  Subject then left the vessel and entered the water to determine if the vessel plug was inserted.  He found the plug was missing and utilized a rubber key chain to stop V1 from sinking.  During the time that Subject was in the water, and due to the rough water conditions, Subject came in contact with the swim platform on the transom of V1.  This caused deep lacerations to his scalp.  He received treatment from EMS on scene, and was then transported by family members to the local hospital.
