    Re: Researchers spoof GPS signals to alter superyacht'scourse

    You are right.   But these were not easily identified (eg, the "high up red lights" were, according to footnote 9, from radio towers on the eastern end of Nantucket Island 30 miles away and "not generally visible to vessels transiting the traffic lanes"   The yellow flashing buoy was one at the beginning of the approach to New York, but according to the report's map of the vessel's path, 20 miles away.    So, yes, there were lights visible to the navigators on the Royal Majesty.   But I have to wonder of what navigational use these sightings would have been, given their distance and the fact that both sightings were directly to the west.

    They spotted lights that they should have taken bearings on, see page 8 and conclusion 9 on page 45.

    Gary, if you're referring to the Royal Majesty, I don't believe your "magic amulet" would have been of use.   The ship was well out of visual range of shore-side objects.

    People who have sailed with me would recognize me with my "hockey puck" compass hanging from the lanyard around my neck all the time. When I am asked what it is I tell them it is a magic amulet and that it keeps rocks out of the bilge. If there is something out there that you can take a bearing on then take the bearing and see if it makes sense when you look at the chart. If there is any doubt then investigate until you are absolutely sure that you are not approaching a danger. Am I an old fuddy-duddy?

    Dan M:
    The problem you describe, or certainly past of it might be put as follows. Some people desire, from minimal input, maximal results, or in other words, A Free Lunch, same being unavailable. Possibly, the students you mentioned and encountered have no real interest in old fashioned Celestial Navigation, as it used to be practiced, preferring to get answers without input.
    I'm as lazy as the next guy or gal, and re other studies, I have played the same sort of silly games, invariably finding that it doesn't work. One gets no more out of something than one is willing to put into that thing.
    Possibly, and this is simply an uneducated guess, some of the fault might lie in and with the controlling agency, the Coast Guard, which correct me if I'm wrong, establishes requirements/qualifications. Perhaps they need to review the requirements that they at least play a role in establishing. Like I said, the foregoing is imply my uneducated guess. I find fooling around with a sextant interesting. Not everyone agrees.
