When the GPS ceases
to work, 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.
This course is offered in an approximate 12-week format.
