Most boat will go slow enough without an adjustment to not make a wake. It is just that people are impatient and don't want to go slow enough. And no, I don't think they need to be stopped for a ripple, although I have seen it done, but I think they should be stopped for a small wake. Believe me after people learn that MP is around and are stopping people for making a wake, you won't see any wakes for a while. And when MP is sitting near a no wake zone there are many less wakes. Magically they are able to drive without making a wake!!!!
