If that sailboat was aground then he was in shallow water, I guess a jetski can play in water that a boater would not. How high could the bow of that sailboat have been? 4-5 ft. and sloping down towards water. The jetski would have had to pass within 20ft of the sailboat at significant speed to cause that injury!
It's hard to feel sorry for a guy that is that ignorant. I feel bad for his family, but not for him. I agree with the Darwinism comment!!! The Earth is getting a little crowded anyway.
