Re. famous and popular workshop "Celestial Navigation: 19th Century Methods"
I would love to jump over the pond to attend your course, and meet folk like you and other Navlist members but unfortunately, I’m mostly grounded these days.
Have you ever considered doing an online course for similarly lost and far away souls?
I’m starting to do time sights by calculator and slide rule and since I like to do lunars, I have quite a few “simultaneous” altitudes of moon and sun. Last year I worked these up as standard LOPs as per M St Hilaire to get a reasonable fix, but this year I hope to experiment with doing it as 2 simultaneous time sights, no plotting, no Azimuth etc and ordinary graph paper.
Vive the old time methods! The Whaling log books are a gem of a find. And I’m old enough to have suffered logs at school in the early sixties before they threw them out in favour of slide rules, (I still have my old School Thornton circa 1964.)
Thanks to Noell Wilson for pointing out an interesting article in the New York Times yesterday discussing a project tracking down "extraordinary imagery" for a book on illustrations of whaling from original logbooks. Read it here. The article also links to the New Bedford Whaling Museum's collection of digitized logbooks available online. As you know, I try to keep up with lists of historical logbooks and journals that have been digitized and made available on the Internet. Of course, there's Mystic Seaport's online collection, which hasn't been updated in a long time, but maybe soon? That collection is here. I would be grateful for any links to others...
While I'm thinking of it, next weekend at Mystic Seaport is another run of my famous and popular workshop "Celestial Navigation: 19th Century Methods" which focuses directly on the analysis of the logbook and navigational calculations made aboard the whaleship Charles W. Morgan in 1896-97. You'll learn to navigate exactly as they did... More details on my website. NavList's Jackson McDonald will be attending this class. Maybe a few other NavListers who haven't yet mastered the fine art of time sights by logarithms might like to join the fun?? :)
