A '''zeppelin loopeye knot''', also called a Rosendahl loop, is a secure, jam resistant fixed size [[:Category:Loop knots|loop knot]] based on the [[zeppelin bend]]. It is one of the few loopseye knots suitable for [[bungee cord|bungee]]. It is also special in its ease of untying.

==Tying==

Virtually all bends (i.e. end-to-end joining knots) have a corresponding 'eye knot'. For example, the Sheet bend (ABoK #1431) has a corresponding eye knot which is none other than the common (#1010) Bowline. The Zeppelin bend is formed from 2 superposed loops of opposite [[chirality]].

The zeppelin bend being a nice knot to attach two ropes; one naturally gets a loop when one of the ropes is the main part, and the other is the working end of the same rope.

There are two versions of the zeppelin loopeye knot depending on how it is tied.

* The first version where the end seems to be vertical to the main part, and one of the loop sides seems to be the continuation of the main part, while the other loop side seems to continue as the working end out of the loop knot. This version is tied using the clover method, starting with an [[overhand knot]], then letting the working end pass in the following order through

# first the eye of the clover ([[overhand knot]]) on the main part side along with the main part (thus forming the loop)

Line 27:

# and last the other eye of the clover knot in the opposite direction of the exiting working end (loop side)

* The other version where the end seems to be the continuation of the main part, and both ends of the loop seems to be vertical to the main part. This version is tied using the clover method, starting with an underhand knot, then letting the working end pass in the following order through

*# - the same eye to form a simple [[noose]] thus forming the loop

*# - around the edge of the underhand knot, and through the loop of the [[noose]]

*# - around and through the knot along with the main part ( thus passing simultaneously through all 3 of the original underhand knot, the noose and the last round of itself).
