[PCW] squatting

[Bob Kupps]

Hi here's one for you NAs - 
   
  I can understand why a hull has a bow-down trim force from a driving sailing rig but what exactly causes the stern to squat under power? If the hull was simply towed from a bow tractor instead of pushed from under the stern by a prop would the same thing happen?
   
  Thanks...Bob
