Fantastic computer graphics teach traditional & modern navigation methods in an entirely practical way. A pictorial manual which teaches you how to navigate in the traditional way using compass and log as well by electronic aids such as GPS, radar and chartplotter.
Great book densely packed with easy to follow information from the basic traditional navigation to electronic and then to celestial. I would have liked to see an expansion of interpolation of secondary ports. As the book is a pdf some of the graphic and text do not come out well on a paper white kindle. Probably better as a hard copy rather than the soft kindle.
