Professional truck driver, Yesterday Irmani, teaches us how to tie a time honored, weight sustaining knot, for transportation purposes.
To tie what is known in Brazil as "the Paulista", make sure to secure one section of your rope around the base of your cargo to something stable. In this case it is linked to the trucks side panel. The other section of it should be a single line that runs over and around your cargo into a strait line of rope that is also secure in the same area. The top section, held by your hands is split into two parts and should resemble an arc/loop connecting atop. Pull both sides up to your cargo, pull the third piece of rope through the arc/loop. Pull the third single piece of rope upward, the arced piece of rope should bend upward with it. Hold this with one hand. Just above this, with the third piece of rope, create a loop and twist it once. Pull the bent single segment up through it and pull it into a secure knot while maintaining a loop. Grab both the loop and the free strait end to ensure it's entangled. Pull downward solely on the free straight end to desired tension. Wrap free straight end once around the two lines at the base of the rope just above source of the rope's security (in this case the trucks side panel). Make sure when you do this you create one loop in each hand with this rope creating bunny ears. One ear will have a long straight piece of rope hanging from it. Pull the first loop (one without the free straight line) through the other. Grab the new single loop and the free straight line, pull tight to secure new knot. As before, simply pull on the free straight line but, instead of to desired tension, simply to further secure the knot.
Simply follow the above instructions and you'll be trucking safely in no time.
