RedactedNarrative: A 20'' Bayliner was returning to Las Vegas Boat Harbor from Black Canon at approximately 2215 hours on 05 September 2014. The vessel operator made a sharp left hard turn approximately 30 feet from the shoreline of South Boulder Island. The vessel came completely out of the water ejecting one passenger into the water. Three other passengers were injured in the vessel. 
             Damage to the vessel is on the hull and lower unit. The navigation lights on the vessel were operational.  The navigation red 4s flashing buoy located at the southeast side of boulder islands was operating normally upon our arrival on scene. The buoy is approximately 1/4 mile from the accident location. The moon was up and in its last quarter phase.
