When docking, which line is used to prevent the boat from moving sideways away from the dock?

• A. Breast line
• B. Spring line
• C. Bow line
• D. Stern line

Answer: (A)

Preventing sideways drift away from the dock is achieved with a breast line. It runs from the boat’s midsection to the dock and resists lateral movement, helping keep the hull close to the dock as wind or current push the boat away. Spring lines control fore‑and‑aft movement along the dock, while bow and stern lines secure the ends. So, the line used to stop sideways movement is the breast line.
