Chart plotter in the cockpit is a device that makes navigation much easier. It replaces or completes readings from classic, analogue indicators. The chart plotter shows the current position of the yacht on an electronically displayed map. It consists of a GPS receiver, screen and software equipped with maps. Until a few years ago it was a very expensive and rather delicate device, that is why the plotter was placed in saloons, usually at the navigation table. Nowadays it is installed in the cockpit, at the skipper’s station, which allows the skipper to correct the course and easily plan the further journey without leaving his post.

What should you keep in mind when using a map plotter in the cockpit?

• Never fully trust the plotter readings. Always confront them with what the skipper and crew see.
• The way of operating the plotter may differ from model to model. When picking up the yacht it is worth asking for basic instructions on how to operate a particular model installed on the yacht or ask for the manual, although such manuals can usually be easily found on the Internet.
• The risk that the plotter will break down is relatively small. However, it is worth protecting yourself by downloading an appropriate navigation application to your smartphone or tablet. It should be remembered that the basis of navigation on the yacht is the knowledge of classical indicators and paper maps.
