And, unfortunately, observation wouldn't seem to be your good side, either. Large ships do push an enormous amount of water out of their way with the bow of their hull right at the waterline, and will push along almost any light object in their path until that object gets pushed to one side or the other, and then possibly gets drawn under the hull and maybe sent under the ship and right toward the props. Dolphins have the ability to stay in the sweet spot for as long as their surfing behavior seems like fun to them.
It's called a displacement wave. It's using the wave created by the push of the boat to propel itself without having to exert itself swimming forward. Try pushing your hand against water next time you're at the pool and you'll see a small displacement wave that occurs in front of your hand. No boat cuts through water perfectly so there's always a displacement wave.
LOL, you really are clueless.
