RedactedNarrative: OPERATOR HAD JUST PURCHASED V1 AND WAS BREAKING IN THE MOTOR.  V1 WAS TRAVELING APPROXIMATELY 63MPH ACCORDING TO HIS GPS. V1 FIRST STRUCK A ROCK JETTY ON THE STARBOARD SIDE JUST IN FRONT OF THE OPERATOR; V1 CONTINUED ONTO THE JETTY TRAVELING APPROXIMATELY 100 FEET BEFORE OVERTURNING IN THE WATER. OPERATOR WAS EJECTED FROM V1 AT SOME POINT. IT IS OF THE OPINION THAT THE OPERATOR WAS RELYING ON GPS TO GUIDE HIM SINCE IT WAS DARK WHILE BREAKING IN THE MOTOR.
