RedactedNarrative: Pontoon was heading east jumping waves. A jet ski came out from the beach. The pontoon was the stand on vessel and the jet ski was on a 90 degree course heading south towards the pontoon. The pontoon operator made a left turn to avoid collision and a wave hit the vessel causing it to capsize momentarily and ejected the operator and occupant. The vessel turned on its own and headed out to sea on power with no one on board. The jet ski and operator are unknown. The pontoon has not yet been found. The operator of the pontoon stated he was wearing the kill switch around his wrist and it slipped off when he was ejected.
