Garmin has acquired Navionics for an undisclosed sum. Navionics is a privately held provider of electronic navigational charts and mobile applications for the marine industry.

“By combining Navionics’ content with Garmin’s BlueChart and LakeVü content, we will be able to offer the best available breadth and depth of coverage to our marine customers,” says Cliff Premble, Garmin president and CEO, in a statement. “Going forward, we plan to retain the Navionics brand and will continue to support Navionics’ existing customers.”

In addition to its popular boating app, Navionics has developed an extensive repository of nautical charts for oceans, rivers and lakes. Many of these charts have been developed with Navionics’ proprietary surveys, done both in the field and with remote sensing such as satellite imagery and airborne laser scanners.

Navionics is headquartered in Viareggio, Italy, and employs more than 350 workers globally. The statement says they will be retained.
