V1's bow struck V2's starboard stern, injuring the occupant of V2.

 At approximately 8:00pm on October 6, 2012, V1 operated by Operator1 was heading south in Cow Key Channel, heading for Coconut Mallory dock. According to Operator1 he was traveling somewhere above 20mph. As he was approaching Cow Key Channel Bridge he had the occupant V1 occupant lower the vessels all around white light. The light is located in a place where it required V1 occupant to stand in front of the helm of the vessel. In doing so she blocked the visibility of the operator.  
V2 had left out of Hurricane Hole Marina and was heading north in Cow Key Channel at approximately 18mph according to the operator. Operator2 was in route to his live aboard vessel. V2 had no navigational lights nor an all around light on his vessel.
 V1's  bow struck V2's starboard stern. V1 pushed over the top of V2 striking Operator2. V1 circled back around to V2. The captain of V1 picked up Operator2 and took him to the Hyatt's dock. V1 then returned to their dock at Coconut Mallory. EMS transported Operator2 to Lower Keys Medical center where he was airlifted to Ryder Trauma in Miami.
Due to the injuries sustained by Operator2 he was unable to secure his vessel. So, I was advised by Lt. to take the vessel and store it in our compound in marathon for safe keeping.  It was arranged on October 16, 2012 with Operator2 to turn the vessel over to his friend; Operator2 suffered multiple fractures and lacerations.
