Today’s sailors rely on GPS for position finding and passage making. But what happens if your electronic navigation systems fail?

This book provides you with simple, practical, get-you-home navigation techniques that could save you in an emergency.
These easy techniques require no complicated mathematics. Learn the principles of navigation and you will have confidence in your decision-making when you need it most. You will also learn how to make simple instruments using materials and equipment likely to be found on every boat, and how to use them at sea.

With colourful and clear diagrams to aid learning, you will be confident in continuing your passage in a safe and seamanlike manner if the electronics let you down.
