Which channel is designated for communications between vessels and the shore?

The correct answer is Channel 9, as it is specifically designated as a hailing and distress channel, intended for communications between vessels and the shore, as well as among vessels. This channel serves a crucial function in maritime communication, allowing boats to establish contact with each other or with shore stations for assistance, navigation information, or emergencies.

Channel 6 is primarily used for intership communications within a specific range and is not designated for communications with shore stations. Channel 13 is used for bridge-to-bridge communications to avoid collisions and facilitate navigation under specific circumstances. Channel 22 is a general radiotelephone channel used for Coast Guard communications but not specifically designated solely for vessel-to-shore communications. Understanding the specific functions and purposes of these channels is essential for safe and efficient maritime navigation, especially when dealing with emergencies or coordinating with shore facilities.
