Celestial Navigation in the Age of Sail

2026:
  • Register Oct 31,Nov 1 ATLANTIC session: 10am-4pm US Eastern time (1500-2100 UT), online.

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what we're doing with actual logbook entries and calculations in the collections of Mystic Seaport Museum, bringing historical documents to life.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

Over the past few years I have taken all of the Celestial Navigation courses taught by Frank Reed at ReedNavigation.com and I recently repeated Modern CN 1 & 2 just for the pure enjoyment that it brought to me.

My interest in CN started a few years ago as I puzzled over how the stars could be used to find one’s position on the earth. I tried to learn CN through self-study, but I couldn’t make the subject matter interesting and realized that this was not the correct approach. You need a skilled instructor that can guide you through the learning process, and that’s what Frank Reed provides.

In a relatively short period of time I had a solid grounding in CN. Frank has unmatched knowledge of CN. His classes are fun, interesting, and sprinkled with historical context and include as much or as little math as you desire. His visual aids were very helpful and the time spent on discussing how to properly use a sextant to take a sight was beneficial. You will learn how to find stars in the night sky by which to navigate. The downloaded course guide is very concise and includes tables that are valid for 5 years into the future.

You don’t need to be at sea to do CN. I live inland and learned in the class how to do land-based navigation with a sextant, either with a large or small body of water to provide a true horizon, or with no water horizon at all.

Going back 250 years, I understand how CN was practiced through the ages, up to the present time with calculator, equations and tables. Thanks to Frank, I take great satisfaction in knowing that I possess a skill that very few people have. I highly recommend his courses.

What a joyful and stimulating experience to enroll in Frank Reed's class, Celestial Navigation: 19th Century Methods. Frank is a skillful and engaging teacher, able to draw students into this fascinating subject, whether they be novice or experienced. His depth of knowledge is tremendous. Participants get a real taste of what it was like to be aboard a sailing ship of the day. I learned much to enliven my own teaching and decode 19th century ship's logs. It is a rare experience, indeed, to have so much thoughtfulness, enthusiasm, and fun packed into two days. This is the way to learn!

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.
