RedactedNarrative: Vessel 2 was anchored and fishing approximately 30-50 feet from two swim rafts. Vessel 1 was towing a tube with three people on the tube. Vessel 1 came around the point and went in a circle with the tube. As Vessel 1 came out of the circle and straightened out their path the operator looked back over his shoulder at the tube. Operator of Vessel 1 then looked forward and saw Vessel 2 in front of him. Operator of Vessel 1 stated he pulled back on the throttle and attempted to avoid Vessel 2, but they were too close and going too fast. The operator of Vessel 2 stated he saw Vessel 1 coming toward them and attempted to yell to them, but nobody heard him. Operator of Vessel 2 then jumped out of the way of Vessel 1 and into the water before Vessel 1 struck Vessel 2 on the rear starboard corner. Passenger of Vessel 2 also tried to leave voluntarily, but the impact with Vessel 1 caused injuries when she hit her own boat.  Both occupants of Vessel 2 ended up in the water. Three of the occupants of Vessel 1 jumped in to render aid to the passenger of Vessel 2. The injured passenger of Vessel 2 was taken into Vessel 1 and then Vessel 1 docked at the incident location pier until medical could arrive.
