Valhallan,
An interesting theory. However, if I may make an observation… In your diagram (very nicely done, by the way) you are showing the bow wave being generated by the hand entering the water. I think if you observe swimmers, you will see the wave coming off the head and shoulders, not the hand. Also this diagram is only showing the leading edge of the wave and not the body of the wave as your other diagram depicted. Yea, I know you have real stuff to do in addition to this. Again this is great work, do you do this for a living?
