Some topics seem to be ideological, that is depending on beliefs. So I admit that the reasons why I have a sextant and each year buy the Nautical Almanac is that I believe that I one day may need them. This belief in turn is founded on other beliefs. I believe that electrical failure may occur. That is, by the way, the reason why I also have paper
charts, even when I have electronic
charts.
I am not quite alone in this belief. The Royal Norwegian Maritime Directory that issues certificates for all kinds of skippers, do that concerning leisure-skippers (up to 50 tons) in to versions, one for coastal sailing and one non-limited waters. The difference between them being that an examination testing for adequate skills in CN is required to be licensed for all waters.
Forgetting about CN is a belief as well, just another belief or perhaps I should say, another faith.
Now one important aspect in my beliefs is that I also believe that I one day will cross the Atlantic ocean. Even though my ship went down last time (in the Bay of Biscay October 2008) I tried. Because I do not believe that I will need a sextant for sailing i the waters between the Scandinavian countries. I need my sextant ( or rather the new one I will need to buy because the last one went down with the ship) for crossing the Atlantic Ocean.
It is not possible to decide which one these two beliefs is the right one. It is only possible to decide which one of the two is the most prudent, when one want to cross the Atlantic Ocean.
