What is the term for the line used to pass messages or signals between boats during towing operations?

• A. Tow line
• B. Bridge line
• C. Message line
• D. Signal line

Answer: (C)

In towing operations, you need a dedicated channel for exchanging instructions and signals that stays separate from the line doing the pulling. This line is called the message line. It provides a reliable way to communicate—whether by verbal messages, flags, or other signaling methods—without the tension or movement of the tow line interfering with the signal. Using the tow line itself for messages can lead to miscommunication or equipment issues, since it’s under heavy load and movement. Other terms describe lines with different primary roles, so none of them fit the purpose as precisely as the message line.
