The accuracy of the GPS should take any of the guesswork out of the situation, but what do you do if something goes wrong? If at the end of a long passage you sight land and cannot recognise any of the features, you will have the choice of turning left or right to locate your destination. If you originally set the course directly for your destination, you won't know which way to turn. One way of avoiding this dilemma is to build an offset into the course that you steer from the word go. Rather than following a direct line between departure and arrival points, offset the course by around 5°.
On today's boats, the situation with magnetic or true bearings and courses is much more complex, and this can lead to errors unless you develop your own system designed to remove any doubt between the use of magnetic and true. Paper charts still use true bearings and courses because that is the way they are arranged, but you can use the inner ring on the compass rose to get magnetic readings. Electronic charts work in much the same way, but here everything is a true reading because you don't have a compass rose and there is no toleration in the system for the use of magnetic bearings or courses.
There are many situations where it’s helpful to know the distance off a point on shore. When you come into anchorage you will often look at the chart and want to find a spot that is quite close inshore. On a passage you will often want to pass a particular distance off a headland, perhaps to avoid rocks inshore. Of course, radar and the electronic chart can give a quick answer to your distance off, but because the margins can be quite small you want a check and the depth of the water is often a reliable guide.
