RedactedNarrative: Watercraft #1 was done fishing for the day and was southbound on the Mississippi River. WC #2 was trolling northbound at approximately .5 MPH on the Mississippi near the Vermillion River. WC #1 was traveling approximately 21 MPH upon impact with WC #2. WC #1 impacted on the starboard bow going over the top of WC #2. Operator #2 was ejected from the boat and passenger on WC #2 had his head hit by WC #1. Operator #2 was able to get back into WC #2. Passenger on WC #1 notified Operator #1 of a person in the water and they turned around. Operator #1 stated he could see the sides and shore, but not in front of WC because a passenger was sitting in the front seat. Operator #2 stated prior to crash they saw WC #1 coming at them and began waving and yelling. Life jackets were being worn in WC #1 but not in WC #2. Alcohol was not a factor. There was damage to both boats.
