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what we're doing with actual logbook entries and calculations in the collections of Mystic Seaport Museum, bringing historical documents to life.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 workshop

Created 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.

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.

Frank, a wonderful course in Lunars. I learned a lot. I admire your teaching skills and your astounding fund of knowledge. I would wish to emulate your style of instruction. Best regards, hope to sign up for your course in Cel. Nav. in Age of Sailing.

The online class "Lunars: Finding Longitude by Lunar Distance" was a very interesting introduction to the esoteric history of lunars as practiced at sea in the pre chronometer 18th century tall ship era. Practical instruction was also done demonstrating the physical process of observing a lunar with a sextant followed by a how to lunar sight reduction example using a pocket calculator, formulae, and tables. A very rewarding experience.

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.
