Inland Waterway Radio Licensing in the United States

The United States has an extensive network of inland waterways — rivers, lakes, canals, and intracoastal waterways — that carry significant commercial traffic and recreational boating. Radio communication on these waterways follows a mix of FCC maritime rules and Coast Guard regulations that differ in some respects from offshore ocean operations.

VHF Marine Radio on Inland Waters

The same VHF marine radio channels used offshore apply on most US inland waterways. Channel 16 remains the distress and calling channel. Commercial towboats and barges on the Mississippi River system and other major rivers maintain watch on Channel 16 and use working channels (13, 67) for traffic coordination.

Who Needs an FCC License on Inland Waterways?

The same rules that apply to coastal recreational boating apply inland:

• Recreational vessels on domestic inland waterways: generally no FCC station license required
• Commercial vessels: licensing requirements depend on vessel size and operation
• Vessels with HF or satellite equipment: licensing required
• Vessels crossing into Canada or Mexico via waterways: international rules apply, license required

The Great Lakes Consideration

The Great Lakes present a specific case — they are domestic waters, but vessels often transit between US and Canadian ports. A vessel crossing from a US Great Lakes port to a Canadian port is making an international voyage and should hold an FCC Ship Station License and have an operator with a Restricted Radiotelephone Operator Permit.

River Pilot Communications

Professional river pilots — who guide large vessels through challenging river channels — rely heavily on radio communication for coordinating with other vessel traffic and with bridge operators. These professional mariners operate under FCC maritime radio authorizations and are well-versed in both the technical and regulatory aspects of maritime radio communication.
