Formerly โ Junior Navigator, Boating 6: Off Shore Marine Navigation (Level 1) will teach when the GPS ceases to work, how to be guided by the sun.
This is the first of a two-course program of Offshore Navigation for the recreational boater. Learn to use a marine sextant to derive lines of position and a running fix from sights on the sun. When you are boating offshore, remember that GPS is not infallible, nor always available. Be confident when no aids to navigation or land objects are in sight.
