Marine Frequencies Card

The Marine Frequencies Card is an essential quick-reference guide containing all of the emergency and operational channels recommended for use by the U.S. Coast Guard. Designed for boaters, kayakers, sailors, and anyone who may operate near or on the water, this card ensures you always know exactly which channel to use when calling for help, coordinating traffic, or monitoring safety broadcasts.

The card is organized into clean, easy-to-read columns for Channel, Transmit Frequency, Receive Frequency, and Notes, giving you immediate clarity on how each channel functions. It includes the International Distress Channel, all major search-and-rescue channels, bridge-to-bridge and port operations,, safety information, non-commercial calling channels, and other critical marine frequencies—each labeled by type of use so you can find the right one instantly.

Whether you're dealing with an emergency, navigating busy waterways, or simply wanting to stay compliant and informed, having these channels consolidated on one durable, waterproof card gives you confidence and capability even without internet access. It's the perfect addition to any marine radio, ditch bag, emergency kit, or vessel logbook.
