"Among all the books in print on modern celestial navigation,
including mine, this one is far and away the most comprehensive,
more so than even the classic tomes-Bowditch's American
Practical Navigator and Dutton's Navigation &
Piloting. It is rich in graphics, detailed in explanation,
extensive in examples. At logical points, there are quizzes to let
you track your progress."
--Hewitt Schlereth, Author of Celestial Navigation in a Nutshell, teaches celestial navigation at the Maritime Institute in San Diego, CA.
