Practical Sailor looks at how skippers navigate today, using GPS (global positioning systems), chartplotters, digital chart, and radar, and how these tools have revolutionized marine navigation. This revolution has resulted in convenience, but has it allowed us to dismiss the basic skills every mariner should have? GPS was intended to be used as an aid to navigation, not as a sole source.
