Zeppelin bend

Pioneering German airships were named after their designer, Count Ferdinand von Zeppelin.

The bow mooring line of one such 1930s craft—the US Navy-owned and -operated Los Angeles—
is said to have been made fast to the ground mooring rope with this knot (and no other) on the
orders of her captain, Lieutenant-Commander Charles Rosendahl. For this reason the knot is

also known as the Rosendahl knot or bend. It is equally reliable in all kinds of modern cordage
and usage.

Grasp both ropes or cords in one hand with the ends drooping to the right (in this instance) (1).
Lead the frontmost working end around both standing parts and tuck it through from back to
front, tying a simple overhand in itself (2). Bring the standing part of the other line across to the
right, in front of its own short end (3). Tuck that short end over two and under two knot parts (4).

The resulting knot consists of two interlocked overhand knots. Pull on both ends to tighten (5).
