Argo 3 Changes How Boaters Navigate
By Paige Foulk
New platform delivers faster navigation engine, improved chart readability, weather overlays, and a foundation for advanced marine data.
BELCAMP, MARYLAND – April 20, 2026: Argo has released Argo 3, the most significant update to the marine navigation platform since its launch. The new version rebuilds the foundation of the app to deliver faster maps, clearer charts, and new data capabilities designed to help boaters plan routes and understand conditions more easily. Digital navigation has become essential for boaters, but many platforms still make it difficult to interpret the information needed to navigate safely quickly. Argo was built with a simple goal: to make navigation easier to understand while maintaining reliable, official chart data. “Boaters don’t need more data — they need clearer information,” said Jeff Foulk, founder of Argo. “Argo 3 focuses on making navigation faster, simpler, and easier to understand whether you’re planning a trip at home or navigating on the water.”
A New Base Map Built for Speed and Clarity
At the center of Argo 3 is an entirely new base map designed to improve both performance and readability. Panning, zooming, switching layers, and building routes are noticeably faster, even in busy waterways. The chart layer is built on official sources including NOAA, CHS, and the U.S. Army Corps of Engineers. Coverage currently spans North America, with international waters expected to be added this year. Dynamic depth contours and depth shading add clarity while keeping charts easy to read. The new base map also provides the infrastructure needed to support additional data layers and future navigation tools.
Integrated Weather Layers for Real-Time Awareness
Argo 3 introduces integrated wind, rain and lightning data directly within the navigation chart, allowing boaters to see conditions in context with their route and surrounding waterways. The new platform architecture also enables additional weather layers to be added soon, including waves, currents and water temperature. By integrating these layers directly into the chart, Argo aims to make complex marine data easier to understand and more useful for real-world navigation decisions.
Dynamic Depth Numbers
Argo 3 also introduces dynamic depth numbers that remain upright as the map moves and allow users to adjust the size, color and density of depth labels. This makes charts easier to read, particularly in shallow or complex waterways.
Looking Ahead
Argo 3 establishes the foundation for the next generation of the platform. Future updates will continue to expand the integration of bathymetry, advanced weather data, and intelligent routing tools designed to support safer and more confident navigation.

Jeff Foulk grew up boating on the Chesapeake Bay where he enjoyed discovering the bay’s many inlets and coves on his 22’ Grady White. In 2019, Jeff formed Argo Navigation and developed a free marine navigation app, Argo, giving boaters the ability to easily route to new destinations, share local knowledge, and connect with other boaters. It has become very popular, particularly among new boaters, quickly amassing nearly 1 million downloads.
