RedactedNarrative: On May 9, 2020, at approximately 1215 hours, Vessel #1 was beached on shore in Swallow Cove, Lake Mead. Occupants #3, and Occupant #4 were jumping from the fixed canopy structure on Vessel #1 into the water. 
  
  Occupant #4 advised that a portion of his clothing caught on the structure when he jumped. Occupant #4 stated that this caused him to tip head first toward the water and his right arm struck an unknown metal object at the stern of Vessel #1. 
  
  The metal object caused an approximately 3.5 in laceration to the upper right arm of Occupant #4. Occupant #4 was treated for his injuries and transported to local hospital for additional treatment.
