It is a fact that since the GPS has appeared more and more skippers have began to be indifferent or even completely ignore the traditional and foremost nautical instruments such as the compass, the divider and the parallel ruler. Their commitment in the electronic "magical" box, which gives us information about everything, is so big that the compass is now a romantic and yet decorative element of Ribs. Therefore, a new danger has come up hiding behind the "blind'' trust in satellite navigation.

Since 1974 when the first GPS satellite was launched, new roads in navigation opened. The GPS system now permits accurate geographic location with an error of only a few metres and allows us to measure distances or find out our route just with the touch of a button.
