The bowline is a simple knot used to form a fixed loop at the end of a rope. The structure of the bowline is identical to that of the sheet bend, except in the bowline the end and the standing part are used to form the knot rather than two ends, as in the sheet bend.

History

A very old knot, the bowline was first mentioned in John Smith's 1627 work, A Seaman's Grammar,[1] though a "curiously intricate knot… akin to the bowline" was discovered on the rigging of the Ancient Egyptian Pharoah Cheops's solar ship during an excavation.

The name "bowline" is derived from the nautical term bow line which, in the age of sail, was a line that held the edge of a square sail towards the bow and into the wind, preventing it from being taken aback.[2]

Usage

The bowline is used mainly to make a temporary loop at the end of a line. Like the other similar knots, it can be made and then secured over an object like a post. Since the bowline is generally tied with working end, it can be passed through ring or other object before the knot is tied. This feature makes the Bowline a convenient and useful loop knot.

The bowline, or more commonly one of its variations such as the double bowline, is sometimes used by climbers to tie the end of the rope to a climbing harness, or the like. The advantage of the bowline in this application is that the knot is easy to untie even after it has been loaded. The disadvantage is that, while it is a very strong knot under load, it has a tendency to loosen up and become untied when it is unloaded and shaken around over a period of time, as might happen during a climb. Several other knots are more commonly used in modern climbing technique.

The bowline is commonly used in sailing small craft, for example to fasten a halyard to the head of a sail. The Federal Aviation Administration recommends the bowline knot for tying down light aircraft.[3]

Tying

A mnemonic used to teach the tying of the bowline is to imagine the end of the rope as a rabbit, and where the knot will begin on the standing part, a tree trunk. First a loop is made near the end of the rope, which will act as the rabbit's hole. Then the "rabbit" comes up the hole, around and under the tree, and then back down the hole. When this configuration is tightened, a bowline has been tied.

The triple bowline knot or a triple bowline on the bight is a variation of the bowline knot that is used to create three loops on one knot simultaneously. As the second name implies, it is possible to tie this knot in the bight without access to the ends of the rope.

The Bowline on a bight is a knot which makes a pair of fixed-size loops in the middle of a rope. Its advantages are that its loops do not slip and it is reasonably easy to untie after being exposed to a strain.
