Lunar Distance and Age of Sail Classes:
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.

Celestial Navigation in the Age of Sail
Winter / Spring 2026:
Navigate like the crew of the Charles W. Morgan! A fast-paced, two-day introductory workshop in the history and practice of celestial navigation in the Age of Sail. Examining original logbooks and notebooks from the Morgan's voyages we'll apply these same methods to modern navigation. By the end of the weekend, you'll have all the tools you need to sail by the Sun and stars across any ocean. And we'll follow a historic whaling voyage of the Charles W. Morgan across the Pacific, a voyage filled with intrigue: an unknown illness, a captain's resignation, and a mutiny, and port calls on tropical islands and the snowy north of Japan.
In this class, we'll learn how to use and adjust sextants. We'll become experts in the classic method of finding latitude by "Noon Sun". We'll also cover in detail the "equation of time", the "analemma", and the mysterious math of longitude ... mysterious on day one, easy by the end of this two-day workshop! Throughout, we will compare what we're doing with actual logbook entries and calculations in the collections of Mystic Seaport Museum, bringing historical documents to life.
This is real navigation, not just a class "about" navigation. Fast and intense, students who complete this workshop will have the basic celestial navigation skills to cross any ocean using the Sun, a sextant, and a few other simple tools, drawn directly from New England maritime history.
All workshops: $ 149 per person, per workshopCreated and taught by Frank Reed, celestial navigation and astronomy consultant on the team that found Shackleton's "Endurance" in 2022. Also a recent guest expert in celestial navigation on Neil deGrasse Tyson's StarTalk on The National Geographic Channel.
- Nine hours of class sessions.
- Before this workshop: no pre-requisites; designed for beginners.
- Some math you'll need: Basic addition and subtraction; good familiarity with the concepts of latitude and longitude; introductory algebra concepts, especially positive and negative numbers.
- Recommended for ages 18 and up, students as young as age 13 welcome.
If you're registered for an online workshop, you're invited to attend hour-long sextant practical sessions in Rhode Island and Connecticut scheduled as weather and other factors permit. These live, in-person sessions are included in your registration for online classes.

I took Frank's 19th Century Celestial Navigation class in April 2013 and really enjoyed it. Not only was the class interesting but my fellow classmates were too; a retired skipper of a ballistic missile sub, the son of the fellow who invented GPS, a teacher, a captain of a Panamax container ship and a fellow who crossed the Atlantic solo - twice!
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.

I have now done every course I think that has been offered so far at Mystic Seaport taught by Frank Reed in the last two years. I found the courses to all be extremely rewarding.
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.
