Re: The New and Improved Celestial Navigation Poll

Good fun, thanks for posting this. I have two sextants (one is an aviation sextant from WWII which is really fun) and am planning to upgrade my daily driver to a Cassens and Plath Horizon Ultra next year.

I think it is... the Melia hotel here has all sorts of Spanish colonial antiques and it sits right there on a table in front of the elevators. I'll do some macro shots next time, there are precision scales on it.

ciao!

Ahh Nicky...It is always refreshing to see that I can reliably count on your misplaced sarcasm.

BTW.

Finished up installing my autopilot yesterday.

One thing I won't do though is "integrate" it into the new Geonav system, about which they gush in Cruising World:

Now you can plot your course without enrolling in one.

Yeah. Sure.

And what about that little disclaimer that states such a system is not to be used for primary navigation?

What worked for our ancestors who put to sea works for us too.

Never lose touch with the basics of seafairing..

Very sad to see you still want to attack and offend me every opportunity and also very sad that you lack even little sense of humor... you're the only one that read it and didn't smile.

cheers,
Nick.

CN is an interesting and useful skill. Many have stated they will learn it after the docklines are cast and timeis more available. I am in that crowd. Just understanding the night stars is a cool thing anyway.

In the meantime, "there's an app for that!"
There is more to taking sights than just pointing a sextant and filling up a form. I would suggest that you familiarise yourself with the full procedure before the “docklines are cast”. You may have to take sights in a cloudy day, on a boat heeling in a disturbed sea and you will need two hands to hold the sextant and the chronometer. I normally hug a shroud with my right arm on the windward side. Like anything else shooting stars require some training and good planning. A good sextant like any good tools will produce far better result and much satisfaction.

thx
Star Navigator Light 32 used to be free.
In OZ I could do with only one book “20xx NAUTICAL ALMANAC COMMERCIAL EDITION”
For greater accuracy I like to fine-tune the Index error.
Be also aware than chart plotters time can be out by few seconds, good to check it with that “lady”
Have fun.

Re: The New and Improved Celestial Navigation Poll

I never tried to do more than 3 stars , but I always tried to do more than one shot on each star and average. I also never found any noticable differance in length of twilight time south of the line compared with north of the line. Just my experiance!_____Grant.

A bit easier on the deck of the 499' training vessel Golden Bear vs a small, private boat. We were encouraged to shoot quickly and many. A lot of 4, 5, lop pinwheels, with some 7 lop pinwheels. CMA was a rather competitive atmosphere. Around 20* N, near Hawaii, was my senior cruise CN course.
