    Actually, I think Rodney is thinking of the _Royal Majesty_ which went
    aground on the Nantucket Shoals in June 1995 due to an unnoticed GPS
    failure.
    
    The _QE2_ nicked the ground in August 1992 near Sow and Pigs Reef at
    the entrance of Vineyard Sound (west of Martha's Vineyard which is west
    of Nantucket). What made it worse was that they knew exactly where
    they were and overruled the local pilot. The pilot suggested a course
    that kept them in deep water, but the captain was trying to make up
    time and chose to cut the corner, believing the charted depth (39 feet
    from the 1939 survey) to be sufficient (_QE2_ draws 32 feet).
    
    After the incident, the US Coast Guard dispatched the survey vessel
    _RULE_ to re-survey the area. In keeping with current practice, the
    rock they found (with the QE2's bottom paint on it) was provisionally
    named "Rule's Ledge", but locals are lobbying to get it named "The
    Queen's Bottom".
