Was at the the end of the day and decided to go fast, 40mph. I didn't account for the 500 extra pounds of people I had in the boat. When I did a turn the boat turned very sharply instead of sliding across the water. A friend holding on to the windshield fell on me and managed to remove my clavicle from it's proper placement. Luckily no one else was injured other than my clavicle and my pride.
