Vessel #1 and vessel #2 were drifting on Lake Allegan near the middle of the west end.  Operator2 said vessel #1 took off pulling an inflatable coming right at him at a distance.  At approximately 100 feet Operator2 turned to starboard, but vessel #1 moved out of the way as well.  Operator2 said he turned to port and vessel #2 speeded toward him.  Operator2 said he could see the operator of vessel #1 looking back at the inflatable.  Operator2 said he hollered and waved.  Vessel #1 saw him at the last minute, but hit him on starboard side, killing Operator2's wife when she was thrown from the boat.
Passenger in vessel #2 suffered a laceration to her front torso from falling inside the boat when the two vessels struck. She was treated by EMS at the scene for a non-life threatening injury.
