What is the primary use of a VHF radio on a boat?

The primary use of a VHF radio on a boat is for communication regarding marine distress and updates. VHF, or Very High Frequency, radios are crucial safety devices that allow boaters to communicate with other vessels and shore stations, particularly in emergency situations. This communication can involve reporting distress, requesting assistance, or providing situational updates, which are essential in maintaining safety on the water.

While VHF radios can be used for other purposes, such as communicating non-emergency information or coordinating with other boats, their most critical function lies in ensuring safe navigation and responding to emergencies. This is especially relevant in the expansive and often unpredictable marine environment, where timely communication can make a significant difference in safety outcomes.
