      Think of the graph of resistance (vertical axis) vs speed (horizontal
      axis). For a heavy hull, there is a point "hull speed" where the
      curve goes up very steeply (the wall). For a light hull, there may be
      an medium increase (the hill), and for a multi, a slight increase
      (the bump).
