RedactedNarrative: Vessel 1 Operator operating a boat with 5 passengers pulling a tube. On the tube were 3 juveniles. As Vessel 1 Operator was approaching the dock, he began to slow up the boat and the tube with the 3 boys was pushed out beyond the wake. Vessel 2 Operator was in idle as they had just pushed off from the dock and were drifting. Vessel 1 Operator was between the dock and the pontoon boat. When the tube being pulled by Vessel 1 went outside the wake, the wake then pushed the tube toward the front of the Vessel 2. Two of the boys on the tube saw that they were going to collide with the front of the pontoon boat and jumped off. The 3rd boy did not and was pushed into the front of the pontoon boat, striking the side of his head against the front fin of the pontoon boat causing  a substantial head injury and laceration.
