Join Andy, Mia & friends in Annapolis in October for another weekend of sailing history and celestial navigation. While there is hardly an argument anymore for celestial as a backup to electronic navigation, it's part of sailing history, and as ocean sailors, we owe it to ourselves to at least have a general understanding of it, I say! Plus, it makes those long night watches that much more enjoyable when you know your place - physically and philosophically - in the universe.

Note that the course officially starts Saturday, but there is an optional happy hour Friday night to chat before the class starts.

Workshop Details

This will be a hands-on workshop, where you'll learn the concepts of celestial and do some actual sextant sights on the docks. Plus, you'll get to hang out with some like-minded people in a cool & inspiring environment! 

Cost is $500, the Workshop is limited to the first 8 people who sign up.
