Usage
The Rolling Hitch is a friction knot used to attach a rope to a rod, pole, or another rope. Unlike many other hitches, it is specifically designed for lengthwise pull along an object rather than at right angles. A common application in sailing is rigging a stopper to relieve tension on a sheet, allowing a jammed winch or block to be cleared.
Warning
Verify tying technique with a skilled instructor where knot failure could cause property damage, injury, or death.
History
In the late 18th Century the knot now known as the "Rolling Hitch" was called the Magnus or Magner's Hitch, and the name Rolling Hitch referred to two round turns and two half hitches. In 1841 Richard Henry Dana, Jr. used the present-day names in his work The Seaman's Friend, and subsequent authors have continued to use this terminology.

Structure
There are two slightly different hitches commonly known by the name of "Rolling Hitch". The Ashley Book of Knots identifies these two variations as "Rolling Hitch(1)" and "Rolling Hitch(2)" and numbers them #1734 and #1735, respectively. Despite the potential for confusion with the older usage, Ashley chose the name "Magnus Hitch" to refer to knot #1736, which is simply #1734 tied with the final hitch made in the opposite direction. Since two distinct variations of the rolling hitch are widely referred to by the same name, and Magnus Hitch may now refer to a different knot than it used to, the use of Ashley reference numbers for these related hitches can eliminate ambiguity when required. Although some sources fail to differentiate by using a separate name, when a Rolling Hitch or Magnus hitch is tied around the standing part of the rope to form an adjustable loop it is typically referred to as a
Taut-line Hitch.
Strength/Reliability
When using a Rolling Hitch, the load should always be applied from the side with the two turns. Ensure the hitch is very snug before applying any strain, else it will not tighten further under load. When hitching to another rope, Ashley and other sources suggest #1735 is the most secure of the three variants. Though effective for moderate loads, the Rolling Hitch cannot be depended on to hold fast under all conditions. Using stiff and slippery modern fiber ropes, the Rolling Hitch may be difficult to make hold at all. Friction hitches with additional wraps and more complex structure may provide more security.
