Tie one rope to another rope, boom, spar, shaft, etc., and pull lengthwise.
The gripping sailor's hitch[a] is a secure, jam-proof friction hitch used to tie one rope to another, or a rope to a pole, boom, spar, etc., when the pull is lengthwise along the object. It will even grip a tapered object, such as a marlin spike, in the direction of taper, similar to the Icicle hitch, but superior. It is much superior to the rolling hitch for that purpose. It is similar to the Michoacan-Martin friction knot used in climbing; The finishing wrap for Michoacan-Martin is in the opposite direction of the Gripping Sailors knot, both ends are then made to carry weight.
