Channel 16 is primarily used for which of the following?

Channel 16 is designated primarily for distress and safety calls. It serves as a crucial communication channel for mariners to convey emergencies and requests for assistance. When a vessel encounters trouble, such as a mechanical failure, capsizing, or a medical emergency, they can use this channel to alert nearby vessels and emergency services like the Coast Guard. This makes it an essential tool for ensuring safety on the water.

While maintaining communication with the Coast Guard is important, it generally happens on other channels after the initial distress call is made on Channel 16. Public announcements and broadcasting severe weather warnings are typically disseminated through different communication methods and channels, not specifically Channel 16. Thus, the primary use of Channel 16 is strictly focused on distress and safety communications, making it vital for effective maritime safety practices.
