Vessels 1 and 2 were Southbound on Lake Eufaula having just left the cut.  Vessel 1 then stopped to allow passengers to use the restroom.  Vessel 2 struck Vessel 1 from behind.  Vessel 2 then went up onto Vessel 1 and slid off the left side of Vessel 1.  Both Vessels then came to rest.  Vessel 2 left the scene while Vessel 1 proceeded to the shoreline to get help for the injured onboard.  Vessel 2 was located the following day.
