It’s time to improve your fundamental seamanship skills. Join the Marion Bermuda Race Team for an Introduction to Celestial Navigation Seminar Presented by Ocean Navigator School of Seamanship at the Sippican Women's Club in Marion, MA on May 4 – 5, 2013.

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 seminar goes hand in hand with the Celestial Navigation Division of the Marion Bermuda Race starting June 14th and is perfect for any sailors contemplating an ocean crossing or a cruising adventure.

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 paper work. (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.
