I can't figure out what it is you are trying to say here. I don't know about
the point of creation but once the wave is created it should act like any
other deep water wave (this is why I proposed a long hull with many waves
along it as the model. There is water in those waves and it is going up and
down. As best as I can tell you are describing a higher speed regime with no
crests along the hull.
