Justin.

No, I'm not at all serious about that. I wouldn't travel anywhere
without at least two GPS devices. However, should I cross an ocean then
I would certainly have a sextant-plus-reduction-tables as a back-up.


And if you drop the sextant over board? Break a mirror?

Awwww, c'mon Bruce, I did put a VBG and a smiley. I'm not advocating a
no-tech ocean crossing, and a GPS gives a much quicker and more accurate
fix than most could manage with a sextant. You have got a sense of
humour haven't you? BTW, my reference to the mast-top windage of your
4ft parabola antenna was not serious either.

Perhaps my British humour is off at the moment, or maybe I didn't catch
you on a good day. I'll try to remember to add more smilies in future.

Have a good day.

Justin.


The last owner, IIRC, of Jester, after his last cross Atlantic race
(the last one he finished) was asked what sort of navigation he used -
he was a past Lecturer on navigation at the RN school - he replied
that he used GPS but did take a noon sight one day and worked out his
position...... using the GPS for the time signal :-)

But your right, I do carry paper charts and while I don't mark a
position I do write down L & L every hour. Reckoned that if the
'letric Navigation dies I will be able to at least figure out a
compass course to somewhere :-)

Cheers,

Bruce
