What Is a Marine Chartplotter?
A chartplotter is a specialized navigation system designed for boating that integrates GPS data with electronic charts of waterways. Unlike a standard GPS device, a chartplotter offers much more functionality by combining features like radar, sonar, and AIS (Automatic Identification System). These systems are built to be reliable in marine environments, ensuring that boaters always have accurate, up-to-date information about their location, water depths, and nearby vessels.
Chartplotters are permanently installed on the boat, typically mounted on the dashboard, making them highly visible and accessible while navigating. The screens are designed for all-weather use, ensuring that they remain readable even under direct sunlight or in harsh conditions. Their robust, marine-grade construction ensures they can withstand the challenges of life on the water, making them ideal for long-distance trips or professional boating. Popular models from companies like Garmin, Raymarine, and Simrad offer a range of features that integrate seamlessly with a boat’s other systems, providing comprehensive, real-time data.
What Are Marine Navigation Apps?
In contrast to chartplotters, marine navigation apps are software-based solutions that run on smartphones or tablets. These apps have revolutionized how recreational boaters approach navigation by offering a more flexible, affordable alternative to traditional marine-grade hardware. With apps like Wavve Boating, Navionics, and AquaMap, boaters can plan routes, monitor their location, and even track weather patterns—right from their mobile devices.
One of the biggest advantages of marine apps is their portability. Instead of being permanently installed on the boat, these apps can be downloaded to a smartphone or tablet, allowing users to take their navigation system anywhere. Whether you’re on a small fishing boat or out on a weekend cruiser, having a marine navigation app on hand means you can easily plan your route and access key charts without needing additional hardware. These apps are also typically more affordable, with many offering free basic features, and premium options for more advanced tools, such as detailed charts or offline map access.

These devices often have a more tactile interface, allowing boaters to quickly navigate through different options and data points without taking their eyes off the water.
On the other hand, marine navigation apps rely on the smaller screens of smartphones or tablets. While apps like Navionics or Wavve Boating have intuitive interfaces, their smaller screens can be harder to read in bright sunlight. While touchscreens are great for quick adjustments, apps are generally less responsive than the physical knobs or buttons found on chartplotters, which can be important when navigating through rough seas. That said, mobile apps are often more customizable and can provide boaters with a level of flexibility in their display options, making them more appealing for casual or weekend boaters who need a straightforward navigation system.
Features Compared Side-by-Side
Chartplotters offer a broad range of features designed specifically for marine navigation. They often include built-in radar, sonar, and AIS (Automatic Identification System) integration, which can be critical for boaters navigating in busy or offshore waters. Many chartplotters also provide autopilot integration, allowing boaters to set a course and let the system manage the steering, ensuring a smooth and safe journey. These devices also allow for detailed chart overlays, such as depth contours, hazards, and weather patterns, making them indispensable for professional and long-distance boaters.
In comparison, marine apps like Wavve Boating and Navionics focus on providing key navigation tools, such as route planning, weather overlays, and tide charts. While marine apps may not have the same high-level integration as chartplotters, many apps have developed advanced features such as real-time hazard alerts, offline charts, and community-driven route sharing. The main advantage of apps is their portability and ease of use, which makes them great for weekend boaters or those who don’t require the heavy-duty features of a full chartplotter system.

Cost Comparison: One-Time vs Subscription
Chartplotters tend to come with a significant upfront cost, often ranging from a few hundred to several thousand dollars, depending on the model and features. Along with the device itself, there are often additional costs for chart updates, software licenses, and accessories like radar or sonar modules. For professional navigators or those who plan to do a lot of offshore boating, the cost of a chartplotter is justified by the reliability, integration, and advanced capabilities it offers. However, for recreational boaters who don’t need all the high-end features, this cost can be prohibitive.
Marine apps, by contrast, are generally much more affordable. Many apps offer free versions with basic features, while premium versions, which unlock additional charts, advanced tools, or offline capabilities, are often available through one-time payments or low-cost subscriptions. For instance, Wavve Boating offers an easy-to-use app with flexible payment options, making it accessible for both new boaters and those on a budget.
