Classical Position Fixing

In the last chapter we noted that the navigator of a yacht is constantly estimating his position, and that this may be done informally, even subconsciously, or formally on the chart. From time to time, the need arises to check the accuracy of these estimates, either because you are in the vicinity of a danger, or because you need a known point of departure for the next leg of the passage. This is done by fixing your position.

There are any number of ways of producing a fix, including electronics, but you should never forget that, at best, a fix tells you where you were when you noted the data. By the time it is plotted, it is already history. The exception is the electronic chart plotter. This produces a 'real-time' position, but even a plotter must be backed up, so it remains vital to maintain a plot by reading the log and noting the time and position regularly. This sound navigational practice defines any fix, however derived, both in time and on the two-dimensional space of your passage across the chart.

For most purposes, fixing offshore or along the coast is dealt with by some form of GPS. The value of the electronic fix will be considered in Chapters 19 and 24, but while it represents the most accurate and convenient answer generally available, it is not the end of the story.

On occasions, a more direct fix will be appropriate, and the time when a navigator can be so confident in his electronics that there is no need for any back-up skills is still years away. The rest of this chapter therefore concentrates on the classical means of obtaining a fix. It goes without saying that these methods should be practised, not left kicking around in some dark locker of the mind until one day they are suddenly in urgent demand.
