Vessel 1 was towing 2 adults on a tube and was headed upstream on the Kaskaskia River.  The river is approximately 100 yards wide where they were operating.  There were two boats traveling behind Vessel 1 also headed upstream.   Vessel 1 made a left hand turn in front of Vessel A causing Vessel A to slow down for the safety of the tubers.   Vessel 1 then continued the turn, (essentially turning 270 degrees) cutting between Vessel A and Vessel B, and losing the two adults off the tube and also accelerating to avoid Vessel B.  Vessel B was forced to shut off his motor to avoid striking or endangering the tubers. The operator of Vessel 1 (blind in his right eye) turned his head to watch the tubers he had been towing and subsequently ran into the bank and grounded the boat and striking multiple trees up on the bank. Five occupants total, the 3 children received cuts and bruises plus 1 mild concussion and were treated by ambulance on-scene. Adult female occupant (is handicapped--partial paralysis from years prior) suffered a bloody nose and bruises, initially refused treatment but went to hospital for x-rays two days later (x-rays were negative).  Operator had bruises but refused treatment.  No serious injuries. Operator was OUI and recorded a BAC of .151
