A typical tether line used in ice rescue is set up with a ________ knot on the rescuers end.

• A. Figure eight
• B. Overhand
• C. Square knot
• D. Bowline

Answer: (A)

In ice rescue, the end of the tether that attaches to the rescuer needs a stopper that stays put under load and is easy to inspect and untie later. The figure eight knot provides a reliable stopper that won’t slip through the rescuer’s harness or around an anchor when tension is applied. It's quick to tie, easy to verify for correct form, and remains secure under dynamic loads common in cold-water scenarios. Plus, it’s forgiving to tie with gloves on and tight lines, which is a practical advantage in the field.

Other knots don’t fit as well here. The overhand can jam and be very hard to untie after it’s loaded; the square knot can capsize or slip under uneven forces; the bowline can loosen with continuous load and is less dependable for a secure, constant end in rescue gear.
