    Hi George;

    The Merrimac ran aground on Sable Island in 1999. http://24.222.2.10/sable/ My multiple GPS failure occured in 2002. These aren't big ships but little boats out number them and their skipperes are less trained and experienced (we hope)

    It's interesting that the same event, the grounding of the Royal Majesty,
    from about 10 years or so ago, came simultaneously to Lisa Fiene's mind,
    and my own, as an example of GPS failure, and it was useful that she could
    remember many of the details that I had long forgotten.

    Isn't it enlightening, though, that the Royal Majesty event, serious though
    it was, and more serious it could have been, from back in the very early
    days of GPS, seems to be the only case that's come to anyone's mind of a
    GPS-assisted accident. Seems to be a pretty good safety record to me,
    though perhaps that's not a comment that's welcome on Nav-L...

    George.
