A boat GPS, or marine navigation GPS, is a device that uses satellite signals to determine and display a boat’s exact location on the water, aiding in navigation and safety. Although the term “boat GPS” focuses on the ability to pinpoint your location on a map, most modern boat navigation systems are combined with chartplotters and other tools/features which greatly enhance a user’s boating experience. Because of this, modern boat GPS devices not only show your position on a detailed map of the water and include topographical details like depth, channels, and other essential boating information, but they also allow the user to mark points of interest, plan routes, and more! Imagine modern boat GPS systems as being a bit like Google Maps, but for water navigation.

A boat GPS works by connecting to satellites to determine your boat’s exact location. This information is displayed on a screen, helping you navigate with key details like speed and direction. It can also integrate with other tools like fish finders and radar to provide a more comprehensive navigation experience.

Detailed Mapping: Provides a comprehensive view of your surroundings, showing water depths, channels, and essential navigational markers.

Waypoint Marking: Allows you to save specific locations for easy reference.

Route Planning: Helps you plot and follow routes to your destination.

Real-Time Updates: Offers live information on your speed, direction, and estimated time of arrival.

Additional Features: Many marine GPS systems come with a variety of extra features, which we’ll discuss in more detail later.

Anchor Safety Alert: A boat GPS can be set to sound an alarm if your boat drifts outside a predefined area while anchored. This “anchor alarm” helps ensure your boat stays securely in place.

Remote Security Monitoring: Many GPS boat navigation systems allow you to monitor your boat remotely via a smartphone app. If your boat moves unexpectedly, the GPS will send you an alert, acting as a security system.

Integrated Navigation and Safety: When connected with other boat electronics, a GPS can manage the autopilot, display radar information on charts, and transmit your location to a VHF radio for emergency calls, adding extra layers of safety and navigation support.

Recommended maintenance for an inboard boat includes regular checks and changes of engine oil and filters, inspections of the cooling system, and testing of the fuel and exhaust systems. Additionally, it’s important to examine the impeller and replace it as needed, check the battery and electrical systems, and ensure the hull is clean and free from growth. Annual winterization and seasonal servicing help protect against damage and enhance performance. Keeping detailed maintenance records ensures timely interventions for optimal operation.

While boat GPS units are essential for navigation, they do have some drawbacks. They can be pricey, often costing hundreds or even thousands of dollars. Additionally, many boat GPS units are overpowered with features that the average boater may not need, making them complex and hard to use. Compared to the intuitive interfaces of modern tools like Google Maps, boat GPS units can seem dated. This complexity is why some boaters are shifting to more modern tools like boating GPS apps, which offer a more user-friendly experience at a significant discount.

There is no single best marine GPS that is right for everyone. The right choice depends on your specific needs, such as desired features, intended uses, and budget. Here are some key factors to consider:

Features: Do you need a basic GPS for navigation, or are you looking for advanced features like fish finding and sonar?

Uses: Consider how and where you’ll be using the GPS. For example, offshore fishing might require more robust features compared to casual lake boating.

Budget: GPS units for boats can range from affordable handheld devices to expensive multifunction displays. Determine your budget to find a unit that offers the best value for your needs.

By considering these factors, you can choose the best GPS for boating that best suits your boating experience.

Here’s a simple guide to help you understand the different types of boat GPS units and choose the right one based on your needs.

Marine Navigation Apps: For a cost-effective and user-friendly option, marine navigation systems apps are ideal. Apps like Wavve Boating offer essential features such as nautical charts, route planning, and weather updates. They are perfect for casual boaters and can be run on a dedicated phone or tablet. Prices for these apps typically range from $10 to $50, depending on in-app purchases and subscriptions.

Basic Handheld or Removable GPS Units: Handheld GPS units are a great choice for those needing something durable and portable. These units offer essential navigation features like chartplotting and can be easily moved between boats. They are rugged enough for marine environments and are priced between $100 to $300.

Robust and Advanced GPS Units: For serious boaters and anglers, robust built-in GPS units provide the capacity for taking advantage of more advanced features like integrated sonar, live depth readings, and detailed chartplotting. These units are more durable and offer precise navigation, with prices typically ranging from $500 to $2,000, depending on the features and brand. Keep in mind instruments like fish finders require additional installation.

Choosing the right navigation system for boats is essential for safe and enjoyable boating. Whether you opt for a simple app, a portable handheld unit, or a more advanced built-in system, it’s important to match your choice to your specific needs and budget. With the right GPS, you can navigate confidently and make the most of your time on the water.
