An evolution with one piece of flotation equipment behind tied between two lines, managed from opposite banks, with one side pulling the flotation out to the victim is called?

• A. Single-line tow
• B. Two-line tethering
• C. Cross-line drag
• D. Dual-ended float pull

Answer: (B)

Two-line tethering uses two lines anchored from opposite banks to control a flotation device that’s carried behind it. This setup lets rescuers on each bank pull and steer the float as needed, extending it outward toward the victim while keeping the device stable and in line with the rescue area. By having two lines, you can adjust tension from either side to counter drift, maintain orientation, and reach the victim more reliably than with a single line.

A single-line tow relies on one line from one side, which can make control and positioning harder, especially in current or wind. A cross-line drag describes pulling something laterally across the surface rather than maintaining a tether between two lines. A dual-ended float pull suggests pulling from both ends of a single piece of gear rather than tying the float between two separate lines. The described method matches two-line tethering.
