I turned around and toward stern to see other boating coming struaght at us .  We yelled and swung awrms around.  Passenger in his boat started screaming just before striking the ream of boat and driving it up over the rear of mine; landing in the water to teh left of my boat.  Upon impact my son and P1 were thrown to the floor and on the seat.  My son was already sitting ont the floor so he was mostly thrown forward.
