Diving Defined: The sport of entering the water from a raised position, often while executing tumbles, twists, and other acrobatic maneuvers. In most dives the upper part of the body enters the water first, and the arms are extended straight over the head.
In this case the diver (Wilky) appears to be frozen between the Pike and Tuck manuever before entering the water in what is commonly referred to as the Flying Watusi/Belly Flop. The water was about 33 degrees.
