RedactedNarrative: Impacted vessel (B) was traveling north, just outside of the marina, and past the green navigational buoys of the channel to the marina on Lake Winnebago Striking vessel (A) was also traveling north, just outside of the marina. Operator of A observed B being operated to his port or left side, a short distance ahead of his vessel A and the left of the green navigational buy. The operator of A continued to travel in the direction of the green buoy. The water conditions were rough/choppy due to high winds coming from the northwest direction. The operator of A increased his speed to attempt to get over the waves, as he noticed his passenger sitting in the bow of the vessel was getting wet due to the wave splash over the vessel. Operator of A while operating the boat in a forward direction had been looking back at his motor to verify the direction of the steering. this was his first time operating this vessel on the water. He then had his attention on the bilge pump switch as he had accidentally bumped it to the on position. While attending to these two activities, along with the increase in speed, his passenger attempted to get his attention to stop, as he was about to strike B. By the time the operator of A could look ahead he had struck B. A ran over B on the starboard side of B, at the back of the boat, then across toward the port side. Operator of A then put his boat into neutral and attempted to maneuver his boat off B. B instantly took on water from the backside of the boat. B sunk to the lake bottom with only bow remaining above the waterline. Both occupants of B were able to be rescued into A by the passengers of A. All parties traveled back to the marina in A.
