RedactedNarrative: VESSEL 1, A 1978 ELIMINATOR BOAT, WAS ATTEMPTING TO LOAD ONTO ITS TRAILER AT THE LAKE HAVASU STATE PARK NEW RAMP.  THE VESSEL''S MOTOR WAS OFF, AND IT WAS APPROACHING THE TRAILER.  AS THE OEPRATOR WAS TRYING TO GET THE BOAT ATTACHED TO THE TRAILER, IT TOOK SEVERAL LARGE WAVES OVER THE TRANSOM.  THE BOAT THEN SWAMPED, BUT DID NOT SINK BECAUSE IT WAS ALREADY PARTIALLY ON THE TRAILER.  THE WIND WAS EXTREMELY STRONG THAT DAY AND THERE WERE VERY LARGE WAVES.  THERE WERE NO REPORTED INJURIES.
