Going Off The Grid! Celestial navigation is making a spirited comeback. This four-day workshop is both a “hands-on, how-to” practical course on celestial navigation. Tuning in to the ocean will make you a better sailor. Anybody can stare at a GPS/Plotter; it takes knowledge and inspiration to navigate.
