Whether you are studying navigation as part of an RYA course or just want to know more about the art of navigation, the RYA Navigation Handbook is highly recommended. Navigation techniques & practices have changed dramatically over the past ten years or so; GPS & electronic chart plotters, in particular, now offer unprecedented levels of accuracy & reliability. The RYA has adapted its Dayskipper, Coastal Skipper & Yachtmaster courses to reflect the fact that many sailors & motor boaters now regard electronic instruments as their principle means of navigation. However, tradition methods still have an important part to play & this book covers them both, giving equal weight to electronic & traditional methods, & to the needs of power & sail.
