How many HF DSC Distress watch channels must a compulsory vessel maintain when underway?

A compulsory vessel underway is required to maintain two HF DSC (High Frequency Digital Selective Calling) distress watch channels. This requirement is essential for ensuring effective communication during emergencies and enhancing safety at sea.

By monitoring two HF DSC distress channels, the vessel is better positioned to receive distress alerts from other vessels and to communicate its own distress signals if necessary. Operating on these channels allows for redundancy in communication, which is crucial in maritime operations where conditions can change rapidly and where reliable communication is vital for safety.

Choosing to maintain a minimum of two HF DSC distress channels aligns with international regulations and best practices within maritime safety protocols. This ensures that vessels can respond promptly to emergencies, whether initiated by themselves or by other vessels requiring assistance.
