Classes in celestial navigation and related topics
Advanced Modern Celestial Navigation
- This workshop is not currently scheduled. It is also offered as a private tutorial, starting at $500 per person, online or at your location (travel expenses at standard rates).
Explore the underlying concepts and math of celestial navigation including spherical triangles, exact azimuth calculations, great circle distance, ex-meridian sights, and other exotic topics. We'll learn refined methods for taking sights and eliminating the smallest errors in sextant observations. We'll explore the principles behind various methods of sight reduction as well as calculator-based azimuth calculations.
Forward-looking, modern, and calculator-based, this workshop is an excellent sequel to our "Modern Celestial Navigation". We'll also look at position-fix by lunars and artificial satellites. More history, more science, more math, more navigation! This class is an excellent sequel to one of our principal introductory classes such as "Modern Celestial Navigation" or "Celestial Navigation in the Age of Sail" or equivalent.
$249 per person, per workshop
Note for online sessions: You may attend an Atlantic session starting at 11:00 am Eastern US time, or a Pacific session starting at 6:00 pm Eastern US time (these start times are equivalent to 1600 UT and 2300 UT respectively for dates through March 13 and equivalent to 1500 UT and 2200 UT beginning on March 14). Currently Atlantic sessions run for 4.5 hours each day on Saturday and Sunday. Pacific sessions run for 3 hours each day on Monday, Tuesday, Wednesday.
Anyone registered for an online workshop will be invited to attend hour-long sextant practical sessions in Rhode Island and Connecticut scheduled as weather and social distancing permit. These live, in-person sessions are included in your registration for online classes.
- Nine hours in online sessions.
- Requirements: A solid background in introductory celestial navigation and familiarity with basic algebra and trigonometry.
I must admit I dreaded two, back-to-back, 5-hour days, but the time sailed by. (Sorry can't resist.) Thank you.
He also included some 17th century data that I needed. I'm neither a mathematician nor a sailer, but a journalist and author.
Fascinating classes taught by a fascinating and capable instructor.
Lunars class is challenging and fun. Frank presents several different recipes for accomplishing lunars, one of which seems almost easy (kind of). Highly recommended for anyone interested in celestial navigation or nautical navigation history.

Frank taught an incredible class on celestial navigation that brought me from novice to some solid understanding of sextants, their history and most importantly their use as a aid to seeing the sea...and knowing where you are on this planet!
Hands on, wealth of knowledge, great resources at Mystic Seaport, he really covered a lot of ground! There was a lot of math but unlike in my youth, I was on the edge of my seat to soak up knowledge!! Frank made it relatable and real. The sextant which is such an iconic tool of the sea, was demystified. By the end of class i felt comfortable with it. I had mastered how it worked, how to read it and how to adjust it to insure its accuracy.
I came away with all of the cheat sheets and understandings of equations and concepts that breathe the life into what you capture through your sextant sightings.
I would highly recommend Frank and believe the Mystic Seaport with its planetarium, an ideal setting for my class with him discovering this timeless tool of the sea.
Frank did a great job keeping the class interesting with visual aids, both on screen and out on the seaport grounds. Frank had also noticed i was interested in the Draken. This is the Viking ship which had made its voyage across the Atlantic and up and down the east coast, resting for winter in Mystic as the troops regroup, gathering resources for another ocean voyage. He took extra time to talk about and show with polarized film the concept of the "Viking Sun Stone" which is a suspected navigational aide the Vikings may have used to traverse the globe as they had.
All in all i would highly recommend this class to any and all folks interested in learning about navigation and sextants. Informative and digestible, but most of all useful to the point where i am comfortable with the instrument and have the formulas needed to continuing to set my sights on the horizon!!
I look forward to more classes to learn more from Frank and strengthen my understandings of celestial navigation!
Several things stand out. The course material is presented in a balanced way, with a well thought mixture of detailed calculation, broken up by historical, factual, and hands-on aspects. This type of teaching is well suited to most, as it provides periods of more intense reasoning with relaxation and humor. Anyone can walk away with new-found knowledge. I also feel that the approach of understanding historical context and a simple practical approach is unique. It has gone a great way toward clearing up a lot of my preconceived ideas and confusions resulting from the many contradictory or esoteric approaches found in various volumes or on the internet.
Very simply, I learned a lot and it went a long way toward clearing up a mess. I was fascinated the whole time. The courses and NavList provide the tools to keep learning even after the course is over. I left able to measure what I see with a more calibrated eye for real world application, and a greater appreciation of human history. I can strongly recommend these classes for the curious, the fascinated, the historian, the hardcore navigator, or the armchair one. There is something in them for all.
I also found the NavList community to be helpful and encouraging as my journey continues. I hope I can undertake even more material in additional courses in the future.
"There is nothing - absolutely nothing - half so much worth doing as simply messing about in boats" (Kenneth Grahame, from the "Wind in the Willows")
The class was also a great resource for my teaching and my own research interests such as the visibility of celestial objects in the daytime (Jupiter and Venus) and the effects of astronomical refraction near the horizon. I hope to take more workshops with Frank.
