Which channel is primarily for distress calls and hailing other vessels?

Channel 16 is designated as the international distress and calling channel for marine VHF radio. It is primarily used by vessels to initiate communication, make distress calls, and communicate emergencies. This channel is monitored by the Coast Guard and other marine authorities to ensure quick responses to emergencies at sea.

Using Channel 16 allows boats in distress to signal their urgency to other vessels in the vicinity, as it is widely recognized and monitored by both recreational and commercial mariners. It is crucial for safety on water, as it helps coordinate rescue efforts and facilitates essential communications between boats in critical situations.

While other channels may serve specific purposes—such as private communications or coordinated vessel movements—Channel 16 remains the primary choice for hailing other vessels and reporting emergencies.
