Tie a half hitch (see page 22) in the nearest line
so that it encloses the second line, as shown in
the photograph.
This knot was used by the US Navy until 1962 to tether its
lighter-than-air ships (zeppelins). Lieutenant Commander
Charles Rosendahl, skipper of the zeppelin Los Angeles and
an American aeronautical hero, reportedly allowed only one
bend to be used on his airship and on his mooring lines, the
zeppelin bend, thus its other name.
