Tow operation: the tow reel angle must be kept to less than what degree?

• A. Less than 20 degrees
• B. Less than 40 degrees
• C. Less than 30 degrees
• D. Any angle

Answer: (C)

When towing, keep the tow line within thirty degrees of the towing vessel’s axis. That small angle ensures most of the pulling force acts straight astern, keeping the pull aligned with the vessel’s direction and minimizing a sideways component. A larger angle raises sideways loading, makes the towed object yaw more, and increases the risk of line damage, tangling, or the line slipping off the reel. So the safer, practical limit is to stay under 30 degrees. Angles smaller than that are acceptable, but once you go beyond 30 degrees the towing dynamics become unstable.
