Crossing knot-based end-of-line loops.

[xarax]

   Using a Crossing knot structure as a base, we can tie Crossing knot "Bowlines", ( in left- or right-hand, and common or Eskimo variations), but also some other interesting end-of-line loops. I do not know if those loops are more secure or strong than their "Bowline" relatives, i.e. the loops where the crossing knot is interlocked with a bowline-type, "proper" collar.
   (See the attached pictures for some simple Crossing knot-based loops.)

   2 more Crossing knot-based loops. If we re-tuck the tail another time, we get more complex, but also more secure loops.

   For an easy comparison, see the attached pictures for the Crossing knot-based Common "Bowlines" ( left- and right-hand variations).

  I do not remember any more why this most simple crossing knot loop shown in the attached pictures was not included in this presentation of variations of crossing-knot-based loops at this thread... I dare to unearth this long dead and buried thread, just to post it, because it is convenient to have them all in the same place. Who knows, may be somebody would tie, try and compare them some time...
  The crossing-knot-based end of line loops have one great advantage and obe great disadvantage, in comparison to the bowlines. They have a very stable nipping loop, where the danger of opening up and degrading to a helix are easily prevented. However, those nipping loops do not nip the legs of the collar as hardly as in the case of the bowlines, because some nipping force is wasted within the turns of the crossing knot s "8" shaped form.
