RedactedNarrative: Vessel I was trolling. As they went into more open waters they experienced larger waves. Water began coming into the vessel and swamped and three people went into the water. Myself and FD retrieved them and the boat. A three year old was transported for suspected hypothermia. He was treated and released. There was property loss and probably some damage done to the 2 OB motors. Owner is going to get me estimate when he can.
