When lashing to a large object
such as a boom, cross each line to
prevent pushing out on sides
of head. See next page.
If you have access to end of
boom, twist each lap. Secure
using double fishermans knot or
other secure knot. See "Lashing
to Bail Using Harken-Supplied
Line" below.
Note sheave direction of rotation when block is under load in ratchet mode. Make sure the block is
facing the correct way before lashing. Use three laps to create six strands. Tie ends using double fisher-
man's knot or other secure knot. Knot can also be located on side of block. Photos are not intended to
teach this knot. See www.harken.com/knots or consult a knot tying book. IMPORTANT! If you are not
comfortable tying this or another secure knot, get help from a professional rigger.
