82. Slip Knot Trucker’s Hitch

An effective lashing is essential when tying boats or gear to a car’s roof

rack. Various knots go by the name “Trucker’s Hitch,” but they all follow the
principle of this version: after tying off the standing end, the working end
goes over the load then down and around the second tie-off point, then up
through a loop knot in the standing part and back down, where it is tied off
to itself with a sliding hitch.

Instructions

1. Imagine that the standing part of the rope (out of the photograph to the top) has already been tied to a
fixed point on the opposite side of the vehicle with a Bowline. The rope has then been thrown over the load
and we’re about to tie down on this side. Begin with an overhand crossing turn.
