  3. Taut-line hitch - Wikipedia

    en.wikipedia.org/wiki/Taut-line_hitch

    One taut-line hitch is tied 15–30 cm from the aircraft and adjusted for tension, then a second taut-line hitch is tied 5–20 cm further from the aircraft and finished with a half-hitch. Wind-induced lift tends to pull the knot tighter, gust-induced oscillations tend to damp-out, and once the half hitch is undone, pushing the lower working ...

  8. Diamond hitch - Wikipedia

    en.wikipedia.org/wiki/Diamond_hitch

    The steps used to tie a diamond hitch with six points of anchorage. In the diagram shown to the left, six points are used, but the top left, right, bottom left and right points can be ignored by simply "tucking" the rope beneath the load to be tied down, provided its shape and size allow, as is the case when the knot is used on a pack-saddle where those four extra points are simply the four ...
