Boat #2 was traveling NB in Zone 12 of Lake Austin pulling a wakeboarder.  Boat #1 was traveling SB in Zone 12 of Lake Austin pulling a tuber. The wakeboarder from Boat #2 fell so Boat #2 made a u-turn to pick the subject up.  Boat #1 made a u-turn from SB to NB and did not see the fallen skier.  Boat #1 then crashed into and ran over the fallen skier, striking the subject on the left shoulder with the propeller.
