RedactedNarrative: V1 WAS PULLING TUBERS WHILE V2 WAS MANEUVERING TO DOCK. COLLISION BY V2 WAS NOT THOUGHT TO BE IMMINENT, BUT V1 APPROACHED AND COLLISION WAS IMMINENT.  TUBERS STRUCK V2 AND RECIEVED INJURIES AND ADMITTED TO HOSPITAL FOR TREATMENT AND RELEASED.  IT IS UNKNOW IF TUBERS WERE WEARING PFDS AS IT WAS NOT NOTED IN REPORT OR NARRATIVE. V1 AND V2 OPERATORS WERE BOTH AT FAULT, BUT NO CITATIONS ISSUED. V1 DID NOT HAVE A PROPER LOOKOUT FOR THE TUBERS. ALCOHOL WAS NOT A FACTOR.
