What Kind Of GPS Do Boats Use?
Boat GPS provides an accurate method for mariners to navigate, measure speed, and determine location which increases safety levels and efficiency for mariners all over the world. The following are the different types of GPS systems for boats:
- Fixed-Mount Marine GPS- Easy to install fixed GPS units is one of the best options for boaters. They often feature large waterproof displays with full coverage of the United States. It is also powered by your boat’s electric supply so no need for other power supplies.
- Handheld marine GPS units- These portable devices are most utilized by smaller boats(kayaks, sailing dinghies, paddleboards, etc.). They are also great backups for larger boats in case of a power shortage. Though they have smaller screens, these devices still get the job done. Handheld GPS is often powered by AA batteries and can be mounted on boats.
- Multifunction Displays- Streamline your electronics with a multifunction display that enables you to integrate various equipment in just one screen: radar, GPS, sonar, weather, video inputs and more. This is the perfect choice if you have very limited space on your boat.

When looking for a GPS navigation system for your boat, you should consider the size of your boat and what type of activity you’re most likely going to do. Check its features and choose a GPS that works for you.
While purchasing a GPS system can be a bit of a shocker when it comes to its price. Just know that if you pick the right one, it’s going to be a very good investment considering how many lives it has saved and countless boating accidents prevented since its invention.
How To Use Boat GPS Navigation
GPS, or Global Positioning Systems, are satellite-based navigation systems which means that they will work anywhere as long as they can receive satellite transmissions. The more signals it receives, the more accurate it is.
Boat GPS may be a bit overwhelming for beginners but the basics of using it are pretty straightforward.
- First, you need to select a waypoint for your boat to follow to reach your destination. You can do this using the cursor of your GPS or use your finger if it’s a touch screen. Hit the GO button.
- A compass should be displayed on your GPS screen and would change direction depending on how you steer the boat. You just need to follow the course that has been charted.
- Head towards each checkpoint on the chart in as straight a line as possible. As you move forward to the first checkpoint, you’ll notice your boat’s position is gradually changing as well.
- Now, all you need to do is follow the next successive checkpoints until you have reached your destination. You can also modify your route and move the checkpoints if you know a faster or more scenic route to take.

As you sail, your boat’s GPS should display obstacles on the way and pop-up warning signs. You should also see the distance of your boat from the ground on the GPS and use it as a reference so as not to go beyond your boat’s maximum depth and hit the ground.
What Is The Difference Between a GPS and a Chartplotter?
Global Positioning System (GPS) and Chartplotter are two technically different terms that are often used interchangeably.
The main difference between these two is that GPS is based on orbiting satellites and will only give you the longitude and latitude of your current location, nothing more.
A Chartplotter on the other hand use that GPS location and plots it on maps stored in its memory.
In essence, all chart plotters use GPS, but not all GPS are chart plotters.
GPS gives numeric code for a certain location in the form of latitude and longitude which can be difficult to interpret. Chartplotter presents a graphical view like a map, making it easier to understand.
Nowadays, it’s common to find chart plotters that are able to provide the best and fastest route to your destination. Some even have GPS chips embedded in them making an all-in-one boat navigation device.
How Do I Choose A Boat GPS?
There are so many GPS navigation devices available today making it quite difficult to tell the good ones from the bad.
And with many technicalities involved, you’ll need to do a great deal of research and consider a number of factors in order to pick out the best GPS for your boats.
