    Thanks for the lead. So far results appear more appropriate to naval
    architects, and on the surface appear to deal with bow waves, as opposed to
    the underwater/downward component.  Over my head.
    
    Given the hull speed = sqrt of LAW x 1.3 can be broken by racing sleds, yet
    it remains a good rule of thumb.  Its simplicity is what I seek.  A rule of
    thumb for LAW when speed vs. theoretical hull speed is impeded by the
    downward vertical pressure wave striking the bottom.
