You might think stress-free navigation sounds like an impossible paradox.

But it need not be. All boaters, whether under sail or under power, need to be able to navigate safely on the water – both to keep themselves and their crew out of trouble and to avoid endangering others.

Yet navigation has often been presented almost as a black art – complicated, full of tricky maths, and with alien concepts to get your head around. Step in 'Mr Stress-Free': having in his previous books presented techniques for sailing and motorboating in an accessible, manageable fashion, Duncan Wells now turns his attention to navigation. He makes concepts easy to understand and the practice of navigation perfectly achievable for all – with minimum stress.

The book covers the basic introductory elements clearly and simply for novices, and progresses through more advanced techniques for experienced navigators, so that there is something for everyone, whatever their skill level. Diagrams, quick-reference tables and flowcharts, explanatory step-by-step photographs, box features, top tips and QR codes – giving access to explanatory videos – are all features that have been much appreciated by readers of Duncan's other top-selling titles.
