What is the diameter of the Tow Line?

• A. 1/2 inch
• B. 1 inch
• C. 2 1/3 inch
• D. 3 inch

Answer: (C)

The key idea here is selecting a tow line that provides enough strength for towing loads while staying practical to handle. A line with a diameter of two and one-third inches offers the necessary strength to handle the shock loads and tension typical in towing a vessel with a small rescue craft, giving a solid safety margin without being overly bulky or hard to manage. The smaller options would not provide adequate breaking strength for tow loads and could fail under stress. The largest option would be unnecessarily heavy and cumbersome to handle during operations. So, two and one-third inches strikes the right balance for reliability and practicality in towing tasks.
