RedactedNarrative: Boat was headed North on Lake Winnebago back to the Fox River where it docks. While on the way North, the weather in the area became very violent, with strong winds, large amounts of ran as well as hail. The boat has an open deck format and was taking water over the front of the boat. The motor for the boat is an inboard motor and cut out due to the amount of water in the boat. The bilge pump could not keep up and the boat flooded. Three of the occupants of the boat were able to put on PFD's, however the driver of the boat was not able to do so and was only able to grab a floatable seat cushion while the boat was sinking.
