Dont do your tricks close to people in the water! I saw the guy last second, went for a dive and just avoided collision.
The numbnuts had plenty of time to avoid you. In fact after his noob sideways slide he actually got an edge and aimed for you. Unfortunately he was either not paying attention, totally out of control, or had no idea what he was doing, or all three.
Main point is he shouldn't be doing that stuff near people (obviously taking a leak) standing in the water.
