one of the most awe-inspiring. It is also essential for every ocean
sailor who wants to be able to fix his position should the GPS fail. Tom
Cunliffe shows you how to master the art in easy stages. Within a few
pages you'll be taking your first sight. From there it is a short step
to plotting your position, wherever you may be on the world's oceans.
Whether you need to pass an exam, want a back-up to GPS positioning or
simply choose to delight in the wonder of the cosmos, this is the
perfect guide. With photographs, charts and diagrams to help your
learning, you will be able to master the sextant and navigate using the
