A Celestial Navigation Practicum

A four-session introduction to the art of celestial navigation focused on observations of the sun and sight solution by hand scientific calculator. Sessions 1 and 2 introduce the concepts, both astronomical and practical; session 3 takes students out to the shore to take actual sun sights with a sextant; session 4 concludes with sight reduction and plotting the results. No sophisticated math is required, although some familiarity would enhance understanding. Although probably not resulting in a complete facility in the process, the student will have experienced all of the tools necessary for this seafaring art.

Customization: Four two-hour sessions; perhaps offered once a week, or on four successive days. All material is provided, including access to sextants. Students will be provided with all course material and a take-home CD of the course.

The Vital Importance of Wood in Early NH
