GPS devices on board
In the open sea, fast and reliable positioning is indispensable, not only when problems occur and fast help is needed, but also for a safe return home. The GPS position is constantly determined, the navigator always sees his current position and can determine the course with the help of the integrated navigation functions. A handheld GPS device can be taken along when going ashore. For most handheld devices with map function, corresponding street or leisure maps are available. In addition, a handheld GPS can also be used on different boats. Chart plotters, on the other hand, usually have to be permanently installed on board. No matter which variant you choose, you should always make sure that the GPS is best suited for the area you want to chart.
Which functions are still advantageous?
By means of a NMEA interface, no matter whether NMEA 0183 or NMEA 2000, you have the possibility to communicate with other devices, such as autopilots, multifunction displays or radios, even from different manufacturers. Make sure that the GPS is WAAS/EGNOS-compatible, as this allows a more accurate positioning. As the owner of a yacht or a boat, you should never do without a tilted and safe GPS device for navigation.
