Bill Anderson, in his Foreword to the original incarnation of this book as The RYA Book of Navigation, wrote 'The technology of navigation is under-going considerable change at the moment.' He was dead right.
Already, we have seen the demise of three of the electronic navigation systems that were described in the first edition, published eleven years ago. Position fixes from the Global Positioning System (GPS), on the other hand, are nearly ten times more accurate than they were then, because the American government has removed the deliberate errors that were originally used to degrade the accuracy available to civilian users. Satellite-based differential systems promise even greater accuracy in the not too distant future, and it is quite likely that a European version of GPS will be operational within the next few years.
At the same time, the cost of electronic navigation equipment has fallen, and the level of sophistication available has risen. Chart plotters, in particular, have developed from being little more than toys to the stage at which they really can be regarded as serious navigational tools, with potentially life-saving advantages.
Despite these technological changes, of course, traditional navigation techniques survive. They may be less important now than they once were, but they are still available as backups to modern technology, and as a means of understanding or cross-checking the information available from the electronics... or even as an interest in their own right, that can be just as consuming and rewarding as boatbuilding, sail trim, or the racing rules.
