"Please accept my gratitude for your two books Celestial Navigation: A Complete Home Study Guide and Hawaii by Sextant. In the last twelve months, with the knowledge gained from your books and my trusty Tamaya sextant, I have cel naved across the southern ocean from Albany to Hobart and then across the Tasman Sea from Sydney to Aukland.
I am a keen sailor who completes internationally in the Dragon class and have sailed from the age of nine but making fiends with the heavenly bodies has been a mind expanding experience of cosmic proportion. I am also now fiends with Abel Tasman, James Cook, Matthew Flinders and William Bligh. What a gift."
—Denis C., February 2018
“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.”
