Our guest speaker in December will be Dominique Prinet.
Dominique is a sailing instructor for all levels at Sail Canada and ISPA, and an Instructor
Evaluator for Sail Canada. He also holds a 60-ton Master's ticket. He was teaching sailing
in Vancouver, in class and on water, for 15 years, until 2015. He sailed in the
Mediterranean, the Indian Ocean, across the Atlantic with a sextant, in the Caribbean,
and along the B.C. Coast. He has published four books: Celestial Navigation and Coastal
Navigation (each with a "Course" and an "Exercises" book)
The one-hour presentation explains the basic concepts of Celestial Navigation:
determination of latitude from a noon site and Polaris; determination of longitude with a
precise time-piece; general case where the boat is on a circle of position centered on the
Geographic Position of the sun; introduction to the Almanac, the Sight Reduction Tables,
and the Marc St Hilaire method.
