Free Celestial Navigation Class


Learn how to use the sextant with a straightforward explanation of the calculations needed for locating one’s position at sea.  

A half-dozen students have attended the two recent celestial navigation classes (March 16th and 23rd, 2023) on how to process a sun sight. The same students are now welcome to take sun sights at Rodeo beach.  We don’t all need to go there on the same day, but we must have a minimum of two students or a maximum of four to proceed.  Please email me with your preferred Thursday to meet at Rodeo beach at 1pm for a one hour session on using the sextant. 

We will continue teaching traditional celestial navigation (using the sextant and 249 tables) at Rodeo Beach near Sausalito.  These will take place on Thursdays at the Arques School.

You will only need a notepad and pencil for this class.  Explanatory notes will be provided.
