Savvy Navvy Expands Global Chart Coverage

Marine navigation company Savvy Navvy has developed an in-house approach to processing and reconciling fragmented hydrographic data – combining official hydrographic data with expert geospatial data analysis to scale chart coverage faster and with greater accuracy.

The latest rollout adds over 2,200 U.S. lakes and several European countries – opening up more waterways for boaters across the globe to explore. Prioritized by where boaters are most active, the latest update includes all major Minnesota lakes, alongside expanding lake coverage in 20 other major U.S. states.

This approach forms part of Savvy Navvy’s broader data processing pipeline, enabling consistent, repeatable expansion into new regions. Through these data pipelines, the company can now deliver faster, more expansive chart coverage, including waters not yet fully covered by official hydrographic surveys.

Besides U.S. lakes, European coverage has also been extended into Estonia, Lithuania, and Latvia – not long after Danish charts from hydrographic offices were also added to the navigation app.

Savvy Navvy, often referred to as ‘Google Maps for boats’, has had over three million downloads globally. Unlike any other boating navigation solution, Savvy Navvy provides smart routing – giving users optimal routes and dynamic ETAs based on real-time data: departure time, chart information, weather conditions, tide, boat specifications, and local regulations. The updated chart coverage is available across both the Savvy Navvy app and its integrated solutions.

Last month Savvy Navvy launched its new waves feature, turning complex wave data into a simple visual view that helps boaters understand how conditions will feel on the water.

Worldwide chart coverage is available on all Savvy Navvy plans.
