Introduction to Celestial Navigation

Event Date/Time

May 4, 2013 to May 5, 2013


Marion, MA- Sponsored by the Marion Bermuda Race
Presented by Ocean Navigator School of Seamanship.

This seminar is a hands-on course covering basic celestial theory, sight reduction of sun, moon, planets, stars, and specialty sights of certain bodies, like the noon sun sight and latitude by Polaris.

The class covers related topics such as time and time zones, sight planning, sextant accessories and offshore navigation plotting techniques, especially dead reckoning. Practical plotting of each kind of sight, as well as celestial running fixes, is covered in detail.

Sextant use is discussed during one session, but no sights actually are taken during the class. The emphasis is on practical use of celestial navigation, with plenty of pencil and paperwork. (Up to a dozen sights are reduced and plotted during the weekend, with numerous additional exercises.) using H.O. 249 and H.O. 229 in conjunction with the Nautical Almanac.

Students will find the Introduction to Celestial
Navigation seminar to be a comprehensive, yet fast-paced, celestial navigation course. Over the past dozen years, alumni have navigated in Marion-Bermuda Races (even won on occasion!) and have made numerous celestial-only ocean crossings.

A review of basic navigation concepts such as chart work, plotting, true to magnetic course conversion, DR, time/speed/distance, etc. is recommended.
