RedactedNarrative: Operator1 was driving a 1989 Master Craft ski boat on Ike Walton Lake and pulling his 25 year old son on a stand up wake board, and had three younger passengers in the boat.  The tow rope being used was 80 ft long.  The pier in front of the residence was 84 ft long and has a L shape that goes to the left at the end.  On the left side of the pier, there was an 1995 Prince Craft deck boat moored / tied up.  The 115 hp outboard motor on this boat extended out into the lake (nose pointing toward shore).  91' out in the lake in front of the pier was an aluminum pontooned swim raft.  Operator1 stated that he decided to pull his son in between the pier and the swim raft to show his son's young daughter her father wake boarding.  As the boat was making the pass between the pier and dock his son for whatever reason had turned out to the left, which took him on a path towards Operator1's pier.  According to (witness/passenger), Wakeboarder never let go of the rope, where he struck the rear corner (#7) of the moored Prince Craft boat.  After striking the boat, Wakeboarder struck the 115 hrs Mercury motor on the Price Craft boat with his head and body.  Wakeboarder ended up face down unconscious in the water.  Impact cracked the fiberglass cowling on this motor.  Operator1 was made aware of the accident by (spotter/witness) where he turned around, and jumped in the lake to help his son.  Other family members who heard the commotion ran down to the lake and assisted in keeping Wakeboarder's face out of the water till EMS arrived.  Operator1 had stated that his son Wakeboarder had consumed approximately 6 cans of beer prior to the accident.  Wakeboarder was air lifted to hospital for he sustained serious injuries from the impact with the boat.
