Identify the situation

The prompt asks to tune the radio to the appropriate channel for the given situation: "You need to hail another vessel."

Determine the standard VHF channel

For hailing another vessel (calling) and for distress/safety communications, the international standard VHF marine radio channel is Channel 16.

Verify the current display

The radio display in the image is already set to "16", which is the correct channel for hailing another vessel before shifting to a working channel.
