BOWLINE

Climber's method

Whereas the sailor makes the
bowline in his hands and then
drops it over the object, the
climber ties this knot directly
around his waist so that he
can adjust the length correctly
as a safety measure before
tackling an ascent.

Method
Take the standing part of rope
with the left hand and form
the turn by pulling the rope
towards you and twisting the
wrist clockwise (1,2,3).
Thread this turn over the wrist
and take hold of the standing
part again (4). Pull the
standing part towards you
through the turn, forming an
eye through which you pass
the end. Having done this,
pick up the end again with the
right hand (5,6,7). Insert the
end back through the turn,
holding the standing part in
the left hand (8). Hold both
the end and the loop securely
and pull the standing part
with the left hand to tighten
the knot (9).
