What is the primary function of the VHF radio?

The primary function of the VHF radio is to facilitate ship-to-ship and ship-to-shore communication. VHF radios enable mariners to communicate effectively over short distances, making them essential for navigational safety and operational coordination at sea. These radios allow vessels to exchange important information, such as positions, intentions, and navigational warnings, thereby enhancing situational awareness and promoting safe navigation.

While other functions, such as monitoring maritime traffic or sending automated distress signals, are important aspects of maritime safety, they are secondary to the fundamental role of VHF radios in enabling direct communication. Weather forecasting, although crucial for maritime activities, is not a primary function of VHF radios, which are primarily used for voice communication on specific maritime channels designated for different types of operational needs.
