Which VHF channels are available for inter-ship communications?

The correct choice includes VHF channels specifically designated for inter-ship communications, which are crucial for navigational safety and coordination between vessels. Channels like 6, 8, 9, and 10 are well-known for their use in communication among ships, allowing vessels to share information like intentions, maneuvers, and safety alerts.

Channel 13 is primarily used for bridge-to-bridge communication in navigational situations, while channel 72 is allocated for recreational vessel communications. These channels facilitate effective and safe interactions between ships, enabling crews to maintain awareness of each other's movements in various maritime contexts.

Understanding the use of these channels emphasizes the importance of having proper communication practices at sea, ensuring that vessels can respond promptly to one another and prevent accidents. Other options do not provide the same set of widely recognized inter-ship communication channels, making the identified choice the optimal selection.
