Vessel #1 was traveling northeast through The Narrows, Lake Mead National Recreation Area.  Vessel #2 was traveling the same direction behind Vessel #1.  Vessel #1 abruptly made a u-turn directly into Vessel #2's path causing the operator of Vessel #2 to turn quickly to port to avoid a collision.  Vessel #2 then had to turn quickly to starboard to avoid hitting the shore line.  During the rapid turning maneuvers, all of the occupants in Vessel #2 were ejected overboard. Vessel #2 continued traveling without an operator until it crashed into the Nevada shoreline, causing severe damage to the vessel.  Vessel #1 departed the scene without offering aid or information.  See attached report of investigation for further information.
