That's just wrong. Waves don't vibrate, so the train track example isn't a good one. The base of any structure moves less than its top. If we were talking about an earthquake, that would be different. Since roll and pitch happens around a ships axis, the closer you are to the axis, the less movement you will feel. If the bottom moved more than the top, ships would be listing over and sinking all of the time, because the base would be too unstable.
