First, as in all seizings, splice an eye in the end of the
seizing stuff. Take a turn around the line, and pass the
end of the stuff through the eye. Pull it taut and double
the stuff back, taking several turns around the line.
Then pass the end under the turns and again through the
eye. Last, tie a clove hitch over the turns and between
the two parts of the line. See views A and B of figure

SEIZINGS
Seizings are used when two lines or two parts of a
single line are to be married permanently. This should
be done with seizing stuff, which is generally rope-laid,
tarred American hemp of 6, 9, or 12 threads. For seizing
small stuff, however, sail twine is adequate.
Many types of seizings were used for special
purposes in old sailing ships, but the four described here
should suffice for Seamen in modern ships.
FLAT SEIZING
Flat seizing is light and is used where strain is not
too great.
