Advanced Celestial Navigation

The second of two consecutive courses are offered which will put the new student of celestial navigation on the path to proficiency in this time honored, defining skill of the competent sailor. No sailor going offshore should be without this knowledge. Even the U.S Navy has re-introduced celestial navigation as a core-competency at the Naval Academy in recognition of the need for redundant capabilities in the event of technical failure, accident or war.
