This VHF Marine Radio Channels guide presents a clear and practical overview of how Very High Frequency (VHF) radio channels are organized and used in maritime communication. It is designed to help seafarers, maritime students, and industry professionals quickly understand the correct use of each channel in daily operations and emergency situations. At the center of the guide is Channel 16, the internationally recognized channel for distress, safety, and calling, highlighting its vital role in emergency alerts and initial contact between vessels and shore stations.
