The Anatomy of a ‘Bowline on the Bight’ (#1080)
Compare with the standard Bowline (#1010)… there are now 2 eyes – a primary eye and a
secondary eye.

Standing part (‘SPart’)

Important Note:
Ashley depicts this knot without a tail. No load

The knot is tied mid-line and there

are 2 SParts which in turn creates 2
nipping loo ps.

The structure depicted at right has 1

SPart and 1 corresponding nipping
loop.

Warning!
Do not load the secondary eye by itself. Both eyes
must be loaded in unison. Catastrophic failure could T1: ‘Tip’ of the primary eye
occur if the secondary eye is loaded independently. T2: ‘Tip’ of the secondary eye
