VBG  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. -- Justin C, by the sea. |

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 (bruceinbangkokatgmaildotcom) |
