The Anatomy of a Standard Bowline (#1010)
Standing part (‘SPart’)
Collar
Note: The collar is a specific
region of the bight structure.
It is where the bight performs
a U turn around the SPart.
The collar has 2 ‘legs’.
Core (nub)
1 2
Legs of the Collar:
Nipping loop 1) entry leg
(a closed helical structure) 2) exit leg
This photo shows a
Bowline based on a right- C
hand helical nipping loop.
Crossing point
Note: A helix can be right- (This also marks the point
handed or left-handed, not where the SPart enters and
as rotating clockwise or becomes the nipping loop)
counter-clockwise.
Handedness (or chirality)
is a property of the helix, S
not of the perspective. A
right-handed helix cannot
be turned or flipped to Region of highest
look like a left-handed one stress & strain
unless it is viewed in a
mirror, and vice versa.
Tail
(begins from exit
point of the nipping
loop to the end)
Tail end
Returning Eye-leg
(ends at the point
where it enters the Ongoing Eye-leg
nipping loop) (begins where it
emerges from
the nipping
T loop)
