Frank creates and teaches all of the workshops in celestial navigation presently offered by ReedNavigation, including all online workshops. Although on-site classes are currently cancelled due to social distancing, he also teaches all of the classes currently offered at Mystic Seaport Museum (MSM), as well as Boston Community Boating Inc. (CBI) and other venues. He is fluent in nearly every technique and tool in celestial navigation from ancient historical methods to the most modern computer-based applications, and is the world’s leading expert in the topic of lunars –the process of determining absolute time at sea by measuring with a sextant the angular distance between the Moon and the Sun (or a selected star or planet).
