Celestial Navigation in the Age of Sail

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what we're doing with actual logbook entries and calculations in the collections of Mystic Seaport Museum, bringing historical documents to life.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