A chartplotter gps device is an absolute necessity if you are planning a trip on open water. Historically sailors were well trained, using compass, skill and instruments such as the sextant to navigate the waters. But accidents did happen and many sailors lost their lives at sea.
Using a chartplotter Gps you can avoid most of the hazards that befell these sailors. The gps receiver will give you your exact location while the chartplotter will alert you to hidden obstacles such as buoys and known hazards in the water. If you are going too close to shore, the system will alert you well before you run aground. The screen must show a nautical chart not just give you the position in longitude and latitude.
All chartplotter gps systems are slightly different and you are best advised to consult the directions of your particular model before using it. Basic functions similar to all models include the tracks function. This allows you to leave a graph of your exact journey so you can follow it on your return. This could be very useful if a deep fog made visibility difficult.
A route planner is another basic feature and this works very similar to a route planner in your car. If you want a more advanced version, it is possible to buy a chartplotter gps device that can be integrated with the boats autopilot. The boat will then automatically follow the course set by the GPS system. With improvements in technology all sorts of things are now possible including the ability of some systems to work with the boats wind instruments and make its own navigational decisions on how best to reach your selected destination.
Most chartplotter GPS systems are installed into the boat although it is possible to buy handheld devices. Obviously the handheld option is the least expensive. You can also buy computer based systems with specially adapted laptops suitable for using in wet conditions.
