This picture on the distributors site would indicate flying high is part of the normal use.
But, anyone that's jumped/dove into the water from that height knows it's easy to get hurt. Plus anyone who owns/uses a boat regularly knows you don't want to hit the water at high speed from any height.
IMO people have to use their heads, are the primary source of their own safety, and are at least partly to blame when injured with sports equipment.
Actually that applies to tools and appliances too.
