Method
Take a rope around the
plank and batten as
illustrated in figures 1, 2,
and 3; then pull the
innermost turn over the
end of the plank (4) to
give a completely
secure grip (5). Finish it
off with a bowline (see
pp. 70-85) (6), but
before tightening the
knot, check that the
support rope on both
sides is perfectly
perpendicular to the
plank.
