RedactedNarrative: V1, a fifteen foot Key West vessel with two occupants was underway on plane in the Peace River near the Hwy 761 bridge. The operator turned into an area he was unfamiliar with running aground on a sandbar. The impact stopped the vessel and both occupants were propelled forward.  The operator struck the helm and suffered no injuries.  The passenger's forward motion caused him to impact the trolling motor which caused a large gash on the left side of his face.  The occupants were able to free the vessel from the grounded situation and made their way back to the boat ramp.  EMS services took the passenger to the hospital to be treated for his wounds.
