RedactedNarrative: Watercraft was pulling a tube. The watercraft was occupied by five people and the tube had one person. The Operator maneuvered the watercraft to move the tube from the left side of the wake produced by the watercraft, to the right side of the wake. While moving toward the right side of the wake, the person on the tube fell off and landed face first in the water. He was brought aboard the watercraft and then taken to shore, at which point he was becoming lethargic. He was then transported by ambulance. All were wearing life jackets and alcohol was not a factor.
