What is the marking interval for drogues?

• A. 50 feet
• B. 30 feet
• C. 60 feet
• D. 80 feet

Answer: (A)

In towing operations, drogues serve not only to add drag but also to give you a way to gauge distance and monitor the tow by reading marks spaced along the line. The marking interval identifies how far apart those distance marks are. Fifty feet is used because it provides a practical balance: the marks are close enough to read quickly and judge how far the towed object is, but not so close that the line becomes cluttered or hard to read in rough seas. This spacing helps you detect and respond to changes in tension, direction, or speed promptly, while keeping the tow within a controllable spread. Smaller intervals would overwhelm the crew with marks and complicate reading, whereas larger intervals would make it harder to estimate distance accurately and react in time.
